Over-the-Range Microwave Swap (Existing Outlet + Vent)
An over-the-range microwave swap from Handis is a two-person, like-for-like replacement of an existing OTR microwave on the existing 120V cabinet outlet and the existing vent (recirculating, ducted up, or ducted back) — from $300, with the manufacturer template, the wall-bracket lag-screw into studs, and the cabinet-bolt thread all handled in one visit. An OTR microwave is one of the heaviest single items in a kitchen — typically 60 to 90 pounds — hung at the most awkward height with the least margin for error. The mounting bracket has to lag-screw into studs behind the back wall (not into drywall alone), the cabinet template has to be drilled exactly per the manufacturer dimensions (every model is different and getting it wrong cracks the cabinet bottom), the vent has to be configured for recirculating or ducted before the unit goes on the bracket, and the lift itself is a two-person job because the angle is brutal. Handis sends a vetted handyman with a partner for the lift, the right templates and bits, and the vent damper hardware for both recirculating and ducted configurations. Existing 120V cabinet outlet and existing vent only — new circuits, new ductwork, or hardwired microwaves route to a licensed Washington L&I electrician.

What Does an OTR Microwave Swap Include?
An over-the-range microwave swap from Handis is a five-step, two-person install — pre-install inspection, old unit removal, blower-assembly rotation for the existing vent path on the counter, wall-bracket lag-screw into studs plus manufacturer cabinet template, and the two-person lift onto the bracket with the cabinet-bolt thread and high-power test — all hung on the existing 120V outlet inside the upper cabinet and the existing vent. The connection has to exist (the outlet inside the upper cabinet, the vent transition through the cabinet bottom or through the wall behind), the wall has to have studs in the bracket positions, and the upper cabinet has to be solid enough to take the manufacturer's cabinet-support bolts. New circuits, new vent runs, or hardwired microwaves route to a licensed electrician.
Pre-Install Inspection
Look inside the upper cabinet for the 120V outlet, check the existing vent configuration (recirculating with a charcoal filter, ducted to a 3-1/4 by 10 rectangular elbow, or ducted to a 6-inch round through the wall above), measure the rough opening width (most OTR microwaves are 30 inches wide and most upper cabinets are 30 inches but the variances matter), and locate the studs behind the back wall using a stud finder plus a pin probe to confirm. About 10 minutes.
Old Unit Removal
Two-person job. Unplug the 120V cord inside the upper cabinet (or stop here if it is hardwired — hardwire removal routes to an electrician). Remove the cabinet support bolts from inside the upper cabinet (typically two long bolts visible from above). Tilt the unit forward and lift it off the wall bracket. Set on a moving blanket on the range top. About 15 minutes.
Vent Configuration
Every OTR microwave ships configured for one of three vent paths — recirculating (factory default on many models, the air vents back into the kitchen through a grille at the top of the front face after passing through a charcoal filter), ducted up through the cabinet bottom to a 3-1/4 by 10 rectangular duct, or ducted out the back through the wall to a 6-inch round. The new unit's blower has to be rotated to match the existing duct direction; this is done with the unit off the wall on the range top before hanging. About 15 to 25 minutes.
Bracket Install
The wall bracket lag-screws into studs behind the back wall — never into drywall alone. If the existing bracket aligns with the new microwave's bracket pattern (most do, some do not, and the variance matters per model), we reuse the existing bracket. If not, we drill the new bracket into the same stud and patch the old screw holes. About 15 minutes.
Cabinet Template + Lift
The manufacturer ships a paper template that aligns to the cabinet bottom and shows the two cabinet-support bolt positions. We drill the template through the cabinet bottom with a 3/8 bit. Two-person lift the microwave up the wall, tilt the bottom onto the wall bracket hooks, then thread the cabinet bolts from inside the upper cabinet down through the cabinet bottom into the microwave top. Plug into the 120V outlet inside the cabinet, latch the door, run a 30-second high-power test for fan and turntable. About 30 to 45 minutes including cleanup.
How an OTR Microwave Swap Works
Five sequential steps from the cabinet check to the two-person lift onto the wall bracket — the actual sequence we follow on every over-the-range microwave swap.
Pre-Install Inspection
Look inside the upper cabinet for the 120V outlet, identify the existing vent configuration (recirculating, ducted up, or ducted back), measure the rough opening width, and locate the studs behind the back wall with a stud finder plus pin probe to confirm. Roughly 10 minutes.
Old Unit Removal
Two-person job. Unplug the 120V cord inside the upper cabinet (hardwire whips route to a licensed electrician), remove the cabinet support bolts from inside the cabinet, tilt the old unit forward, lift it off the wall bracket, and set it on a moving blanket on the range top.
Vent Configuration on the Counter
Rotate the new microwave's blower assembly to match the existing duct direction (recirc, ducted up, or ducted back) while the unit is still on the counter — trying to rotate after the lift is the most common rework cause. New recirculating units get a fresh charcoal filter.
Bracket + Cabinet Template
Verify the wall bracket lag-screws into studs behind the back wall — never drywall alone. If the existing bracket aligns with the new model we reuse it; if not, the new bracket goes into the same stud and old holes get patched. Tape the manufacturer template to the cabinet underside and drill the two cabinet-support bolt holes.
Two-Person Lift + High-Heat Test
Two people lift the microwave up the wall, tilt the bottom onto the bracket hooks, and thread the cabinet-support bolts from inside the upper cabinet down into the microwave top. Plug into the 120V outlet, latch the door, run a 30-second high-power test for fan, light, and turntable.
Over-the-Range Microwave Swap Pricing
Final pricing depends on the cabinet condition, the existing bracket alignment with the new unit, and whether vent reconfiguration is needed. Two-person lift included by default for the safety and the cabinet protection. Request a free estimate for an accurate quote.
Send us the new microwave model and a photo of the existing vent — recirc, ducted up, or ducted back. We will quote the visit and tell you upfront if a new circuit is needed.
Why Homeowners Book Handis for OTR Microwave Swaps
Over-the-range microwaves are the appliance category where the install fails most often — typically a single person trying to hang a 75-pound box on a wall bracket at chin height, with the cabinet template misaligned by a quarter inch because the new model's bolt pattern is not identical to the old one's, with the vent rotated wrong because the blower assembly direction was not changed before the lift, and with the lag screws driven into drywall instead of studs because the previous installer did not actually find the framing. After a few hundred OTR microwave installs across Seattle kitchens, every one of those failures has a check that happens before the new unit comes off the counter. We confirm studs, align templates, configure the vent, and bring a partner for the lift itself.
Existing outlet and vent only, and we say so on the call
This is a plug-in swap on the connections already in the cabinet and the wall. New 120V circuits, extension of an existing circuit, new vent ductwork, conversion from recirculating to ducted (or reverse) that requires opening the wall or the cabinet to add new duct, and any hardwired microwave installation route to a licensed Washington L&I electrician. The blower-rotation vent reconfiguration on a unit that supports both modes is part of our scope; cutting new duct openings is not.
Two-person lift by default
A 75-pound box hung at chin height with the bracket-hook tilt move and the cabinet-bolt thread from above is a two-person job. We send a partner on every OTR microwave install — the lift safety and the cabinet protection (no scraped cabinet faces from a one-person tilt) are worth more than the few minutes of cost on the visit. The two-person lift is included in the base price.
Studs confirmed before the bracket goes on
The wall bracket has to lag-screw into studs behind the back wall. We confirm stud positions with a stud finder plus a pin probe (the pin confirms the finder against false reads from foil-backed insulation or wire runs). If the existing bracket aligns with the new microwave's bracket pattern we reuse it; if not, the new bracket goes into the same stud and the old screw holes get patched. Drywall-only bracket installs are the most common cause of OTR microwave failures.
Vent rotated correctly before the lift
The new microwave's blower assembly has to be rotated to match the existing vent path — recirculating, ducted up, or ducted back. This is done on the counter, with the unit accessible, before the lift. Trying to rotate the blower after the unit is on the wall is the most common rework cause on OTR installs. We read the new model's installation manual against the existing vent before the unit comes off the counter.
Manufacturer template, not eyeballed
The cabinet-support bolt positions are different on almost every microwave model — the template that ships with the new unit is the only reliable way to drill the cabinet bottom correctly. We tape the template to the cabinet underside, drill with the spec bit, and verify the bolt fit before the lift. The old template holes (from the old microwave) usually do not align; we patch them flush so the cabinet bottom is clean.
Estimate
Tell us the new microwave model, the existing vent configuration (recirculating with charcoal filter, ducted up through the cabinet, or ducted back through the wall), and a photo of the cabinet underside and the wall behind the existing unit. We will quote the visit and tell you upfront if anything routes to a licensed electrician.
Customer Reviews
Over-the-range microwave swap reviews from real Handis customers.
New GE Profile OTR microwave on a 12-year-old Whirlpool. The tech and his partner showed up together — said the lift is always two-person for safety and to keep from scraping the cabinet face. Read the new unit's manual against the existing vent (we were recirculating; the new unit shipped configured for ducted) and rotated the blower on the counter before the lift. Bracket reused, cabinet template re-drilled, new charcoal filter. Hour and a half total.
Old microwave had a vent that ducted out the back through the wall. New Samsung had a different bracket pattern entirely — the tech said the existing bracket would not work and installed a new one into the same studs, patched the old holes flush. The blower rotation he did on the counter; the install took longer than a clean reuse but the duct path was the same. Two and a half hours including the patching. Microwave is rock solid.
Existing space had a range hood, not a microwave. The tech said the OTR conversion needs a wall bracket lag-screwed into studs since a range hood mounts differently. He installed the bracket, drilled the cabinet bottom for the new template, and the existing 120V outlet inside the upper cabinet worked. Three hours start to finish — about an hour longer than a straight swap but the result is a clean OTR install in a space that was a hood.
Multi-appliance kitchen day. The OTR microwave was the longest part — the cabinet template on the new LG was offset two inches from the old Frigidaire and the old holes had to be patched with wood filler and re-drilled. The tech showed me the difference before he drilled and confirmed we wanted the cabinet bottom patched flush. Looks like the original cabinet now. Microwave is up, vented, working.
I was told by the previous handyman that my OTR microwave install needed a new circuit because the kitchen wiring was old. The Handis tech checked the existing outlet inside the cabinet first — read 120V steady, no flicker, on a dedicated circuit at the panel. Said the new circuit was not actually needed and gave me a $200 install instead of the $600 the other guy had quoted. Honest scope, saved me real money.
