Frequently asked questions
Why is my microwave running but not heating food?
The magnetron has failed — it is the part that actually generates the microwave energy and it is a wear item with a 7 to 10 year typical life. Symptoms are exactly what you described: turntable spins, lights work, fan runs, but food stays cold. Magnetron replacement is $250 to $420 depending on brand. On a unit older than 10 years we will tell you straight whether replacement makes more sense.
How much does microwave repair cost?
Built-in and over-the-range microwave repairs run $180 to $420 including parts and labor. Door switches, turntable motors, and fan motors are on the lower end; magnetrons and high-voltage capacitors sit at the upper end. The $59 service call is free with an approved repair.
Do you service built-in and over-the-range microwaves?
Yes — built-in (cabinet-mounted), over-the-range (OTR with combined hood vent), microwave drawers (Sharp, Wolf, Thermador), and countertop units. Built-in and drawer units take more access labor because of the cabinet trim and bracket mounting, which we quote up front.
My microwave is sparking inside — should I keep using it?
Stop using it immediately. Internal sparking is almost always a damaged waveguide cover (the small mica or plastic panel inside, easily replaced) or a failing magnetron arcing to ground. Less commonly it is metal contamination on the cavity walls. Continued use damages the magnetron permanently. Call (754) 345-4515 for a same-day diagnostic.
Why is my microwave touch panel unresponsive?
Most common cause is a failed membrane keypad — the conductive contacts behind the buttons wear out after 8 to 12 years of use. Less common is a control board failure where the main board no longer reads the keypad input. Membrane swaps are quicker and cheaper. We diagnose which it is on a $59 service call.
Can you fix a microwave with a broken door?
Door latch assemblies, hinges, and the interior door switches that confirm the door is closed — yes, those are all repairable parts. A cracked door glass or a bent door frame on an over-the-range unit is sometimes worth replacing the whole microwave instead. We quote both options honestly.
Do you handle over-the-range microwave install and removal?
Yes — including the wall mounting plate, cabinet bracket, exhaust vent connection (recirculating or ducted), and electrical hookup. Install runs $195 to $295 depending on whether the wall mount needs reinforcement or new ducting. We haul away the old unit on the same visit.
Why does my microwave turntable not spin?
Three usual suspects: the turntable motor below the cavity floor has failed (the most common cause), the roller guide ring under the glass tray is missing or broken, or the coupler that connects the motor shaft to the tray is cracked. All three are inexpensive fixes — motors stock for GE, Whirlpool, Samsung, LG, and Sharp.
Can you do same-day microwave repair in Miami?
Yes, same-day and next-morning slots are usually available across Miami-Dade and Broward when you call before noon at (754) 345-4515. Built-in and over-the-range units get priority because removing them takes more lead time than a countertop swap.
How long should a microwave last?
Countertop microwaves typically run 7 to 10 years. Over-the-range and built-in models last 10 to 15 years because they get less rough handling and are usually cooled by a real exhaust fan. Magnetrons are the limiting part — once they go, the math on a $300-plus repair against a $500 replacement gets close.
Do you fix microwave drawer units like Sharp and Wolf?
Yes — Sharp KB6 series, Wolf MD30, Thermador MD24 microwave drawers all in our regular service mix. Drawer units have a more complex track and door system than over-the-range units and we send senior technicians on those calls. Parts often order in 2 to 4 business days because they are brand-specific.
What is your warranty on microwave repairs?
Tiered parts coverage plus a 90-day labor warranty. Parts we install are covered up to 10 years on sealed-system welds, up to 2 years on mechanical parts, and up to 1 year on electronic and electrical components. Labor is backed for 90 days — parts up to 10 years on sealed-system welds, 2 years mechanical, 1 year electronics; labor 90 days for the component we replaced. Magnetron and high-voltage capacitor work carries the same coverage. Same-failure callbacks inside 90 days are no-charge.

Microwave repair in Miami — built-in, over-the-range, and drawer units
If your microwave runs — turntable spinning, lights on, fan going — but food stays cold, the magnetron has failed. It is the part that generates the microwave energy and a 7-to-10-year wear item; replacement runs $250 to $420 depending on brand. Internal sparking is different: stop using it immediately, because it is almost always a damaged waveguide cover (cheap and easily replaced) or a magnetron arcing to ground that gets permanently worse with every use.
Most of our Miami microwave work is built-in and over-the-range rather than countertop, because that is what is mounted in condo and high-rise kitchens here — cabinet-mounted units, OTR models with combined hood vents, and drawer units like the Sharp KB6, Wolf MD30, and Thermador MD24. Those take more access labor to remove, which we quote up front. Unresponsive touch panels are usually a worn membrane keypad (quicker, cheaper) rather than a dead control board; we confirm which on the $59 service call.
Built-in and over-the-range repairs run $180 to $420 including parts and labor — door switches, turntable motors, and fan motors at the low end, magnetrons and high-voltage capacitors at the top. We also handle OTR install and old-unit haul-away ($195 to $295). Turntable motors stock for GE, Whirlpool, Samsung, LG, and Sharp. Same-day and next-morning slots are usually open across Miami-Dade and Broward when you call (754) 345-4515 before noon.

What kind of problems are we working with?
Not Heating
Microwave runs and the turntable spins but water stays cold—that’s magnetron, HV capacitor, HV diode, or the door interlock circuit. We discharge the capacitor first (it holds 2,100–2,500V even unplugged), then ohm the magnetron filament (should read under 1Ω) and check the diode in both directions. KitchenAid/Whirlpool over-the-range units (W10727360 magnetron family) and Wolf MDD30 drawers fail on the diode more often than the magnetron. Magnetron jobs typically $260–380.
Turntable Not Turning
Plate dead but cavity heats means the synchronous turntable motor (3 RPM, 21V or 120V depending on model). Pull the floor plate, unclip the motor, ohm the coil—open circuit replace. Coupler under the glass can also shatter and slip. GE Profile and Samsung over-the-range units share a common 3-pin motor; Wolf and Miele built-ins use a different mount and 21V drive. Turntable motor + coupler typically $140–190 done.
Strange Noises
Grinding from the back panel is usually the magnetron cooling fan bearing or the stirrer motor. A high-pitched whine while heating is HV transformer lamination buzz—normal up to a point but if it doubles in volume the transformer is failing. Whirlpool/KitchenAid built-ins get fan bearings around year 7; Bosch HMV series fan motors are sealed and replace as an assembly. We always test under load with a water cup, never empty. Fan jobs typically $180–240.
Door Issues
Three interlock switches sit behind the door frame and they fire in a specific sequence. If even one is misaligned the unit won’t start, runs without heating, or trips the line fuse on door close. We pull the door, check switch continuity in both states, and inspect the latch pawls for cracks—a single broken pawl on a GE Profile or Whirlpool can throw the whole sequence. Bosch and Miele built-ins use a slightly different cam. Interlock service typically $160–220.
Sparking
Arcing in the cavity is the waveguide cover, a stripped wall paint chip, or a magnetron antenna cap that lost its mica. The mica cover is a $6 part but you have to pull the magnetron to swap it. If sparking comes with a burn smell we replace the magnetron together because the antenna is often already pitted. Wolf and Thermador built-ins use a ceramic-faced cover that handles arc damage better. Waveguide + cover service typically $150–220.
How to fix your machine?
Tell Us What's Failing
Runs but doesn't heat, sparking, display dead, door switch fault, turntable not turning short description plus a model plate photo speeds up the diagnosis.
Built-in & Over-the-Range Both Covered
Wolf microwave drawer, Miele speed oven, Thermador built-in, GE Monogram trim kits we service all of them. Diagnostic fee waives with the repair.
Magnetron, Door Switch, High-Voltage Diode
Magnetrons and door interlocks need same-visit replacement with proper safety (capacitor discharge first). Control panel work is scheduled separately if a board is on order.
Built-in Installation Matters
Most built-in microwave failures combine an electrical issue with poor original installation. We re-seat the unit during the repair when needed at no extra charge.
Heat-Up Test Before Closeout
Cup of water for one minute must boil. Door interlock cycled five times. Followup call inside 48 hours.

Microwave repair by brand — how the failure modes differ
Over-the-range microwaves that double as the kitchen hood are the volume call — when the vent fan dies the fix is a blower assembly, not a hood motor. GE, Whirlpool, and Samsung OTR units fail at the magnetron, door interlock, and membrane panel; built-in and drawer microwaves from KitchenAid, Bosch, Wolf, and Sharp get OEM panels and high-voltage parts. Magnetron and capacitor work is handled with full HV-discharge safety procedure.
