What we actually do on an RV furnace call in Port St Lucie
We diagnose ignition, airflow, propane supply, control board, and thermostat issues, then repair or replace the failed component on the spot if parts are in-stock. We carry Suburban and Atwood/Dometic boards, igniters, sail switches, limit switches, motors, and common thermostats on the truck. We also perform leak checks and CO safety tests before we leave. You get heat that holds temp and a written 12-month warranty.
Ever had the furnace click but never light? Or it lights, then shuts down after 30 seconds? We see that every cold snap here. Salt air and humidity on the Treasure Coast chew up sail switches and corrode grounds. Our fix isn’t guesswork. We meter gas pressure, verify 12-volt power under load, and test the flame signal so you don’t replace parts you don’t need.
Pricing, timelines, and what’s included
Here’s the thing. You want straight numbers. So here they are. Diagnostic is $129 in Port St Lucie, waived with repair. Typical rv furnace repair totals:
- Sail switch or limit switch replacement: $189 to $285 parts and labor. Igniter or flame sensor: $225 to $325. Control board: $295 to $495 depending on model. Blower motor: $375 to $585.
Most services take 60 to 90 minutes. A full annual furnace service is $169 per unit and includes burner cleaning, orifice inspection, electrode gap set, combustion air path clearing, amp draw test, and LP leak test. We’re licensed and insured, and we back furnace repairs with a 12-month parts and labor warranty. Questions about cost in Tradition or St. Lucie West? Same pricing, no surprises.
Common failure point: clogged or sticky sail switch. We stock Dometic and Suburban OEM.
Signs your RV furnace needs repair and the fix you’ll likely need
If your blower runs but there’s no heat, expect an ignition fault. Nine times out of ten it’s a weak igniter, dirty burner, or a failing control board. Short cycling, where it warms for a minute then shuts off, often points to a blocked return or a bad high-limit. If it lights only when your batteries are on shore power, you’ve probably got low 12-volt voltage or a dragging motor. And if you smell propane, stop and close the tank, then call us. We carry combustible gas detectors to confirm any leak.
Last month near Tradition Square, a 2017 Winnebago wouldn’t light unless the owner banged the side panel. Classic sail switch sticking. We swapped it, cleaned the blower housing, reset the electrode gap to 0.125 inch, and the unit fired perfectly. Total time, 55 minutes. Total bill, $239 out the door.
Our mobile rv repair coverage across Port St Lucie and the Treasure Coast
We’re based in , , and we work the entire St. Lucie County area plus the Treasure Coast. If you’re off Crosstown Parkway, US-1, Becker Road, or around St. Lucie West, we’re usually 25 to 40 minutes away. We also service Jensen Beach, Fort Pierce, Palm City, Hobe Sound, and Vero Beach. Camped at Savannas Recreation Area or near Tradition Regional Park? We’ve probably got a tech right around the corner.
Emergency rv repair slots open daily in season. Same day rv repair is first-come, first-served, with after-hours calls available at time-and-a-half. If you prefer shop service, we’ll set a bay time. Either way, call or request a free estimate, and we’ll lock your spot.
The quick DIY checks before you call us
If you like to tinker, here are safe checks that solve about 20% of calls. No special tools needed.
1) Verify propane and 12-volt power. Open the tank valve, light a stove burner to purge air, and confirm battery voltage is above 12.2 volts. 2) Set thermostat to Heat and 5 to 10 degrees above room temp. Replace thermostat batteries if your model uses them. 3) Check all return and supply vents. Don’t block under-bed returns or kick-panel grilles. Clear pet hair and dust. 4) Reset the furnace. Turn the thermostat Off for 60 seconds, then On. If accessible, pull the 12-volt fuse for a minute and reinsert. 5) Inspect exterior intake and exhaust ports. Mud dauber screens clog. Clear debris gently and try again.
If it still won’t fire, don’t keep cycling it. You’ll flood the chamber and stress the board. Call and we’ll handle the rest.
Safety and code: propane, CO, and RV furnace standards you should know
Propane appliances in RVs are covered by NFPA 1192, the Standard on Recreational Vehicles, and most manufacturers follow RV Industry Association guidance for installation. Florida’s LP Gas Safety Program is administered by the Florida Department of Agriculture and Consumer Services. They require licensed work on LP systems and leak checks after service. We follow those rules every day, because they’re there for a reason.
According to Suburban’s service manual, a proper flame should be steady blue with minimal yellow tipping. We measure manifold pressure at 10.5 to 11.5 inches water column for propane, per manufacturer spec, and we soap-test every connection we touch. We also recommend a CO alarm less than 5 years old. Cheap insurance. You can read more from the National Fire Protection Association and RVIA for background.

Common furnace brands we service and the parts we keep on the truck
We stock parts for Suburban SF and SH series, and Atwood/Dometic AFM/AFMD 25-35-42-50K BTU models. On board daily: Dinosaur Electronics and OEM control boards, igniters/electrodes, sail switches, limit switches, motors, grommets, burner assemblies, and thermostats from Coleman, Dometic, and Emerson. We carry manometers, UEI CO meters, and Fieldpiece multimeters for testing. Honestly, we skip off-brand replacement boards unless you insist. Too many callbacks.
If you run a diesel hydronic system like Aqua-Hot, that’s a separate service with different pricing. We handle those too, but we’ll schedule a longer slot and bring filter kits and nozzles.
Our daily truck stock covers 80% of furnace failures in one visit.
Why furnaces fail more often along the Treasure Coast
Humidity and salt air. They attack connections, grounds, and motor bearings. Add beach sand in returns and mud daubers in the exhaust, and you’ve got a perfect storm. We see a 35 to 40 percent spike in furnace calls after the first cold front in November. Units sit all summer while you chase AC issues, then the first cool night exposes weak igniters and sticky safeties.
We’re big on prevention. A $169 fall service beats a $495 board swap every time. If you store near the coast, use screened vent covers, keep returns clear, and run the furnace for 10 minutes each month, even in summer. Sounds silly. Works.
Preventive maintenance plan: what we do each fall
Our annual service checklist is simple and effective. We clean and inspect the burner and orifice, set electrode gap, verify 12-volt supply and ground resistance, test motor amp draw, check sail and limit switch operation, confirm LP system pressure, and test for leaks. We also vacuum returns and supply ducts you can reach, and we photograph before and after so you can see the difference.
Takes about 45 to 60 minutes per furnace. If you’ve got a toy hauler with two units, we discount the second service to $139. We recommend this every fall on the Treasure Coast. You’ll sleep better when that first north wind hits.
