RV Microwave Repair in Fort Lauderdale
An RV microwave that stops heating, loses all power, or trips the circuit breaker is a significant daily inconvenience - and in Fort Lauderdale's heat, it often coincides with the conditions that stress appliances hardest. Our mobile appliance specialists diagnose and repair RV microwaves and convection microwave combos throughout Broward County, carrying the most common failure parts for same-day resolution at your campsite or driveway.
Broward County's humidity creates RV microwave failure patterns that our team addresses regularly. Moisture infiltrates microwave control boards through temperature cycling, oxidizing the solder joints and trace surfaces that keep the control circuitry functioning. The door interlock switches - small spring-loaded contacts that prevent the microwave from operating unless the door is properly closed - corrode and fail in Florida's persistent humidity. Power quality at older campground shore pedestals causes magnetron stress and protection fuse failures. Our appliance specialists understand all of these Fort Lauderdale-specific failure modes.
RV Microwave Types and Their Failure Patterns
Standard OTR Microwave Units
The over-the-range (OTR) microwave is the most common type found in RVs - a compact unit mounted beneath the overhead cabinet above the kitchen counter or stovetop. These units use the same magnetron-based heating technology as residential microwaves, scaled down to fit RV cabinetry dimensions. Common brands include Contoure (designed specifically for RV use with a low-profile form factor), RecPro, Sharp, GE, and LG residential units installed as replacements. The failure modes are universal: magnetron failure (no heat but everything else works), door interlock switch failure (complete non-function), blown internal fuse (complete non-function, often from shore power surges), and control board failure (intermittent or complete non-function).
Convection Microwave Combination Units
The convection microwave combination unit adds a convection oven function to a standard microwave, using an internal electric heating element and a fan to circulate hot air. This allows the unit to bake, roast, and broil in addition to standard microwave heating. In an RV, this is a significant feature because it eliminates the need for a separate propane oven - useful in Fort Lauderdale's heat when running a propane oven inside the RV raises interior temperature substantially. Furrion is the dominant brand in RV convection microwave combos. Convection-specific failures our team handles include: convection heating element failure (element burns out, leaving microwave function intact), convection fan motor seizure (fan stops turning, convection mode overheats and shuts down on thermal protection), and combined control board failures that affect both functions simultaneously.
Combination Range-Microwave Units
Some RVs, particularly older Class B vans and compact Class C units, use a microwave positioned directly above the propane rangetop with a shared ventilation system. These combination placements create additional heat and grease exposure for the microwave unit. Our appliance specialists clean and inspect the ventilation path on these units as part of every service call, since grease accumulation in the cavity between the range and microwave can be a fire hazard if left unaddressed.
How Florida's Power Quality Affects RV Microwaves
Campground shore power quality in Fort Lauderdale and throughout Broward County is genuinely variable. Older shore power pedestals at parks like T.Y. Park in Hollywood or some of the coastal campgrounds in Deerfield Beach deliver voltage that can drop to 105 to 110 volts under load. The microwave's magnetron is designed to operate at 120 volts - when voltage drops below 108 volts, the magnetron generates less microwave energy per cycle and operates at higher current draw to compensate, accelerating wear on the magnetron and high-voltage capacitor.
Power surges at campground shore power pedestals - which occur when other campers connect large air conditioning units or electric vehicles - can blow the microwave's internal ceramic fuse, leaving the unit completely non-functional. The fuse replacement itself is inexpensive (under $5 for the fuse), but finding the fuse location inside the microwave chassis and safely replacing it requires disassembly - a job for our appliance specialists rather than a DIY fix given the stored charge in the high-voltage capacitor.
Using a quality surge protector with low-voltage cutoff is the most effective preventive measure for protecting your RV microwave and other appliances from campground power quality issues. Our team can advise on appropriate surge protection products when on site.
Diagnosis Process
Our appliance specialists follow a structured diagnostic sequence for RV microwave failures. First, we check the circuit breaker and the internal ceramic fuse - two inexpensive components that cause total non-function when they fail. Next, we test the door interlock switches with a continuity meter - there are typically two or three interlocks, all of which must close for the microwave to operate. If the fuse and interlocks are intact, we test the control board for proper voltage output to the magnetron circuit. Finally, we test the magnetron and high-voltage capacitor with appropriate safety procedures. This sequence identifies the failed component before any parts are ordered or installed.

RV Microwave Repair FAQ - Fort Lauderdale
When an RV microwave runs (the turntable spins, the light is on, the timer counts down) but does not produce heat, the magnetron has almost certainly failed. The magnetron is the vacuum tube that generates the microwave energy that heats food. It is the most expensive component in a microwave and its failure typically means the fan, control board, and turntable are all still functional. Our appliance specialists test the magnetron with a continuity meter and check the high-voltage capacitor and diode before confirming the diagnosis, since those components can also cause no-heat symptoms.
Total loss of power to an RV microwave is most commonly caused by one of three things: a blown internal fuse (RV microwaves contain a ceramic fuse that fails under power surges, which are common when connecting to campground shore power with varying voltage quality), a failed door interlock switch (a safety device that cuts power if the door latch does not close properly - these corrode in Broward County's humidity), or a failed control board. Our appliance specialists check the fuse first since it is a $2 part that causes complete shutdown when blown.
A convection microwave combination unit adds a heating element and a convection fan to a standard microwave, allowing the unit to function as a small convection oven for baking and roasting. In an RV, this replaces both a separate microwave and a separate oven. Furrion manufactures a popular RV convection microwave combo. We service both the microwave and convection oven functions - common convection-specific failures include the convection heating element burning out and the convection fan motor seizing, both of which leave the microwave function intact but disable the oven capability.
Yes, and it is one of the more common failure patterns we see in Broward County. The control board in an RV microwave is exposed to the same humidity as the rest of the RV interior. In a full-timer RV in Florida's climate, the control board goes through repeated thermal cycles - cool nights, hot days - that cause condensation to form on board surfaces. Over time this oxidizes solder joints and trace surfaces, causing intermittent failures (the microwave works sometimes but not consistently) that eventually become permanent. The door interlock switches, which use spring-loaded contacts, are particularly vulnerable to humidity-related corrosion.
Microwave diagnosis runs $89 to $149. Magnetron replacement runs $175 to $295 including parts and labor. Door interlock switch replacement runs $85 to $165. Control board replacement runs $125 to $245. Internal fuse replacement is under $75. Convection element or fan motor replacement runs $95 to $195. All pricing is provided in a written estimate before any work begins. We always evaluate whether repair versus replacement is more cost-effective given the age and model of the unit.
Yes. Campground shore power in Fort Lauderdale and Broward County varies significantly in quality. Older shore power pedestals, particularly at T.Y. Park in Hollywood and some of the older campgrounds on the south Broward coast, can deliver voltage below 108V under heavy load - well below the 120V standard. Low voltage causes the magnetron to operate outside its design parameters, generating excessive heat and shortening its life. Power surges when other campers connect large loads can blow the microwave's internal protection fuse. Using a surge protector with low-voltage cutoff on your shore power connection is the best preventive measure.
A microwave that trips the circuit breaker typically indicates a magnetron that has shorted internally and is drawing excessive current, a failing high-voltage capacitor that is not properly discharging, or a shared circuit that is overloaded by the microwave running simultaneously with another high-draw appliance. Most RV microwave circuits are 15 or 20 amps dedicated to the appliance. Our appliance specialists check the circuit breaker rating, the shore power voltage, and the microwave's current draw before recommending a component replacement.
Door interlock switch replacement takes 30 to 60 minutes. Fuse replacement takes 20 to 40 minutes. Magnetron replacement takes 1 to 2 hours. Control board replacement takes 1 to 1.5 hours. In most cases the repair is completed in a single visit. The exception is magnetron replacement for less common microwave models where the magnetron must be sourced - in that case we provide the diagnosis, order the part, and complete the repair on a follow-up visit typically within 1 to 2 business days.
Our appliance specialists service Furrion, Contoure, RecPro, Sharp, GE, LG, Panasonic, and other residential-grade microwaves installed in RVs, as well as the Thetford brand combination units found in some European-style RVs. We carry door interlock switches for the most common OTR microwave footprints and can source magnetrons for most brands from Broward County's appliance parts distributors within 1 to 2 business days.
For RV microwaves under 8 years old, repair is almost always more cost-effective than replacement when the repair cost is under $250. For units over 10 years old or when the magnetron fails (the most expensive repair), the comparison between repair cost and a new Contoure or RecPro unit (typically $150 to $350 retail) becomes closer. Our appliance specialists give you both options - the repair quote and the replacement cost - so you can make an informed decision. We do not push repairs on units where replacement clearly makes more sense financially.
