Most microwave calls we run are units that have lost magnetron output (no heat) or convection-oven units where the heating element has burned out. RV microwaves and convection ovens live in tight cabinets that stress every component differently than a residential install - vibration loosens internal connections, humidity corrodes the high-voltage capacitor leads, and the constant on/off cycling on a generator or inverter shortens magnetron life. We carry Furrion, Dometic, Panasonic, and Whirlpool units in stock plus the trim kits that match standard RV cutouts so most swaps finish in one visit.
Signs your RV microwave or convection oven needs replacement
Four patterns cover almost every microwave call we run. If your rig is doing one of these, the diagnosis is usually quick:
1. Runs but produces no heat
Magnetron is dead. Repair cost approaches the price of a full unit, so replacement is the right call - $385-$685 for a Furrion or Panasonic swap.
2. Sparks or burning smell inside cavity
High-voltage capacitor failure or arcing on the waveguide. Stop using immediately - replacement is the only safe fix.
3. Trips breaker when you try to run it
Internal short or capacitor leak drawing too much current. Replacement, plus check the dedicated 20A circuit before installing the new unit.
4. Convection element won't heat (combo units)
Convection element burned out on a Greystone or Insignia combo. Element-only swap is rarely cost-effective - replace the unit.
What we install - mobile RV microwave service
How we replace your RV microwave from start to finish
We remove the old unit, install the new one, test it hot, and leave you with a working kitchen in one visit - usually 2 to 4 hours. First step is power-down and circuit isolation. We kill the breaker, disconnect the power cable, and confirm zero voltage with a multimeter.
Then we unbolt the microwave from its mounting bracket (usually four bolts, sometimes screwed into the cabinetry). On RVs, the microwave often sits in a tight over-stove or over-counter space, so we photograph the routing of the power cord before removal.
New unit goes in with OEM or equivalent aftermarket brackets - we use Dometic or Panasonic replacement units depending on coach compatibility and availability. All connections get hand-tightened to spec, never over-torqued.
We installed a Panasonic 1100-watt inverter-friendly microwave in a Grand Design Momentum at our Boise yard last Thursday. The original unit was a Whirlpool that had cooked for eight years and finally gave up.
Customer wanted the same footprint and wattage to avoid any power-distribution rewiring. We had the Panasonic in stock, so no delay.
Removal took 35 minutes, install took 45 minutes, testing and cabinet reassembly took 20. Customer signed off, and we billed flat-rate at $280 parts-and-labor included.
What happens during replacement:
- Kill power at breaker and confirm zero voltage
- Remove old microwave from mounting brackets
- Disconnect power cable and any ventilation ducting
- Install new unit with OEM or equivalent brackets
- Reconnect power cable to correct circuit
- Run 3-minute heat test with water to confirm function
- Check door seal and latch operation
- Reassemble cabinetry trim and test final fit
Pricing for RV microwave replacement - flat rate, no surprises
Flat rate is $180-$380 depending on unit type and location, with labor and parts bundled. A basic 600-800 watt Panasonic or Whirlpool replacement runs $180-$240 including 2.5 hours of labor. A higher-output Dometic 1000-watt or inverter-compatible unit costs $280-$380.
We quote you by phone before we roll - no hidden fees, no "oh, that'll be an extra $100 to remove the old one." If you supply your own aftermarket unit, labor-only is $120-$150. We serve our covered metros from our mobile bays at no travel charge within 25 miles of our core areas (Tampa, Ocala, Jacksonville, Boise, Meridian).
Beyond that, a mileage fee applies. Partner network jobs nationwide run flat-rate plus local partner markup, typically $200-$450 total.
A Tiffin Allegro owner in Clearwater had a failed Dometic unit and wanted to install a lower-wattage Panasonic to ease his generator load. He bought the Panasonic new online for $165.
We charged him $120 labor to remove the old Dometic and install his unit, plus $25 for the new mounting bracket. Total bill: $145.
He saved money by sourcing the part himself, but most customers prefer we handle it - they get parts warranty and one-stop accountability. That's our model.
What drives pricing:
- Unit wattage and output capacity
- OEM vs. aftermarket availability
- Existing cabinet configuration fit
- Power distribution circuit capacity
- Geographic location and travel distance
- Whether you supply the part or we do
The actual parts we install and why we choose them
We stock and install Dometic, Panasonic, and Whirlpool units because those are the brands RV manufacturers use as OEM and they're field-proven. Dometic 1000-watt units are the gold standard for full-time RVers and larger Class A coaches - they heat fast and play nice with inverters. Panasonic 800-900 watt units are the workhorse in mid-size travel trailers and Class C motorhomes - reliable, affordable, and widely available.
Whirlpool units are common in lower-cost production rigs like Coachmen and Keystone units. We avoid no-name Amazon microwaves - we've seen two fail within 90 days.
Parts cost us $140-$280 depending on model. We don't mark up parts beyond cost-of-goods; our margin is in labor efficiency.
A Winnebago View customer in Tampa needed a replacement for a 15-year-old Panasonic unit. We recommended a current-model Panasonic 900-watt inverter-ready unit - same footprint, same power draw, full 2-year manufacturer warranty.
Customer approved, we installed it, and he got the manufacturer's paperwork and our 90-day workmanship overlay. If the Panasonic fails in the first two years, Panasonic covers parts and shipping; if we messed up the install, we cover labor to fix it. That dual-coverage peace of mind is why we stick with tier-one brands.
Common RV microwave components:
- Magnetron tube - converts electrical energy to microwave radiation
- High-voltage transformer - steps up 120V to ~2000V for magnetron
- High-voltage capacitor - stores energy for magnetron ignition
- Door interlock switch - cuts power when door is open
- Control circuit board - manages timer, power levels, and fan
- Mounting brackets - secures unit to cabinetry
- Power cord and connector - delivers 120V AC from shore or inverter
How fast we show up and how long the whole job takes
We respond in 2-4 hours for emergency calls in our core service areas (Tampa, Ocala, Jacksonville in Florida; Boise, Meridian in Idaho). If you call at 8 a.m. with a dead microwave, we're at your location by 10 a.m. or noon, and you're cooking again by 2 p.m. or 3 p.m. Standard non-emergency scheduling typically fits you in the same week, often within 48 hours.
Replacement itself takes 2-4 hours depending on how tight the cabinet space is and whether we need to rewire any power distribution. Most jobs finish in 2.5 hours.
If we're swapping one unit for an identical Dometic replacement and the brackets align, we're done in 90 minutes. If you're upgrading from 600 watts to 1000 watts and the cabinet needs modification, add an hour.
A Forest River Class A owner's Dometic unit died on a Tuesday in our Jacksonville service zone. He called at 9:15 a.m., and our tech was at his RV park by 11:30.
Cabinet work was minimal - the mounting bolts lined up perfectly with a replacement Dometic unit we had in the truck. Three hours later, including a full diagnostic check and cabinet reassembly, the customer was testing his new microwave.
He paid flat-rate $320, got a 90-day warranty on our work, and a 2-year manufacturer warranty on the Dometic. Total time from call to finish: 3.5 hours.
Typical job timeline:
- Emergency response: 2-4 hours from call to arrival
- Power disconnect and safety check: 10 minutes
- Old unit removal: 30-45 minutes depending on bracket type
- New unit install and bracket alignment: 45-60 minutes
- Power testing and heat cycle: 15 minutes
- Cabinet trim and final fit: 15-20 minutes
- Total on-site time: 2-4 hours
Our warranty and what's covered if something goes wrong
We guarantee 90 days of workmanship warranty on every replacement - if we mess up the install, we fix it free. This covers loose connections, improper bracket alignment, or power-delivery errors caused by our work. You also get the manufacturer's warranty on the part itself - typically 2 years on Dometic and Panasonic units for parts failures unrelated to installation. If the magnetron burns out six months after we install it, Panasonic or Dometic covers it, not us. If we overtighten a bracket and crack the mounting frame, that's on us. We've filed zero warranty claims on microwave installs in five years because we install to spec and test every unit before we leave.
A Keystone Passport owner in Ocala had us replace a Whirlpool unit in March. Four months later, in July, the door interlock switch failed - a manufacturing defect.
The customer called us first; we confirmed it was the switch, not our work. We contacted Whirlpool, got a replacement switch shipped to the customer's address, and guided him through a 15-minute DIY swap over the phone.
No charge to us or him. Our warranty covered our labor, the manufacturer's warranty covered their part. That's the right way to do it.
What's covered under our 90-day warranty:
- Loose or incorrect power connections
- Improper mounting bracket alignment
- Cabinet damage caused during removal or install
- Blown circuits due to our installation error
- Door latch or seal issues we introduced
- Non-function due to incorrect wiring by us
