AC motors (alternating current motors, typically 115V or 120V single-phase) in RVs, campers, motorhomes, and other recreational vehicles primarily drive the air-moving components in roof-mounted or ducted air conditioning systems and sometimes auxiliary fans or heat pumps. In rooftop RV AC units (like Coleman Mach, Dometic, or Furrion models), a permanent split capacitor (PSC) AC motor powers the condenser fan (outdoor propeller-style fan) to expel heat from the condenser coil, while another PSC AC motor often drives the indoor evaporator blower or squirrel-cage fan to circulate cooled air through vents or ducts—ensuring efficient cooling when the RV is connected to shore power, a generator, or inverter setup that provides 120V AC.
…
DC motors (direct current motors, almost always 12V DC in RVs) in recreational vehicles, campers, and motorhomes are primarily used to power air circulation in propane-fired forced-air furnaces (brands like Suburban, Atwood/Dometic Hydro Flame, or Hydroflame), where a small permanent magnet DC blower motor drives the squirrel-cage blower wheel to distribute heated air through vents and ducts throughout the RV—essential for safe combustion and even heating without relying on 120V AC power.
These motors run directly off the RV's 12V battery system (or converter when plugged in), allowing the furnace to operate efficiently during boondocking, dry camping, or generator-free scenarios, with typical draws of 5–9 amps during blower operation; they often feature dual-shaft designs (one for the main air blower, one for combustion air intake) and are compact, vibration-resistant, and brush-type for simplicity and cost in mobile applications.

Electrodes serve an important function in propane based furnace systems, specifically ones used in RV's and campers. They serve a dual purpose as both the spark igniter and the flame sensor in most modern electronic ignition setups, using a single rod or assembly (often a 1- or 2-prong design) positioned near the burner ports. The control board sends high-voltage pulses through the electrode to create a visible spark across a small gap (typically 1/8" to 1/4") to the grounded burner or a separate ground probe, igniting the propane-air mixture when the thermostat calls for heat and the gas valve opens—ensuring reliable startup in the compact, mobile environment.
Once the flame is established, the electrode acts as a flame sensor via flame rectification: the flame's ionization creates a tiny DC microamp current (rectified by the flame) that flows from the electrode (now acting as a probe) through the flame to the grounded burner and back to the control board, proving flame presence and allowing the board to keep the gas valve open for continuous heating; if the signal is lost (due to dirty/coroded electrode, poor gap, weak flame, or wiring issues), the board shuts off the gas to prevent unsafe gas release, often leading to lockout after retry attempts and requiring cleaning, gapping, or replacement to restore reliable operation.

Restore optimal air flow performance to your ventilation fan, air conditioner fan or blower by replacing the fan blade, impeller or squirel cage wheel. Broken, damaged and deformed bladed can cause a loss of performance and even lead to noise and motor failure.

The gas valve in an RV heating system (propane forced-air furnace, such as Suburban SF-series, Atwood/Dometic Hydro Flame, or similar models) is an electrically operated solenoid valve (typically 12V DC) that acts as the primary safety and control device for propane flow, opening only when commanded by the ignition control board after all safety conditions are met—like proper blower airflow (via sail switch), no over-temperature limits, and sufficient battery voltage—to allow propane to reach the burner assembly for ignition.
It regulates the precise amount of propane delivered to the burner for efficient combustion, remains open during normal heating operation once flame is proven (via flame rectification through the electrode), and immediately closes upon loss of flame signal, thermostat satisfaction, or any safety fault to prevent gas leaks, explosions, or carbon monoxide buildup—making it a critical redundant safety component in the compact, mobile RV environment where reliable, automatic operation on battery power is essential. Common failures (e.g., stuck solenoids, coil issues, or leaks) often cause no-heat symptoms, clicking without gas flow, or intermittent lockouts, and replacements are straightforward plug-and-play parts for these systems.

Ignition modules and controllers are the electronic "brain" that orchestrates the safe startup and operation of your RV's propane fired heating system. If you're unable to start your furnance or heater, have intermittent ignition or lockout issues, you could have a control module that needs replacing.

A slideout motor (also called a slide-out actuator motor) is a 12-volt DC electric motor that powers the extension and retraction of an RV’s slide-out room.
It drives the mechanical system — whether rack-and-pinion, cable, ball-screw, or Schwintek-style gears — to smoothly move the slide room in or out, giving you significantly more living space when parked. These motors are a common replacement item because they’re exposed to weather, vibration, and heavy use, and failure typically results in a slide that won’t move, moves slowly, or makes grinding noises.
They’re found on almost all modern RVs with slide-outs from brands like Lippert (Power Gear), Schwintek, and others.
…
Properly operating water heaters and RV furnances require various switches. Vacuum switches verify airflow prior to ignition and prevent overheating. Limit switches, specifically high limit switches, serve as a safety mechanism to prevent overheating conditions. They are closed by default and open as the temperature rises above the designated safety cutoff temperature.

Need help finding the correct blower or fan kit for your fireplace? Let our experts help you track down the correct replacement blower, fan kit or part for your application. We typically only need the fireplace or stove's make and model to determine exactly what you need. This information can usually be found on gas fireplaces by removing the lower access panel and finding your fireplace's name tag or identificaton card. Wood inserts will often times have the same identificaton card, while freestanding stoves and others might have this information printed on a rear panel or door.
Once you've located your fireplace's brand and model information, simply use the Find Your Blower tool above, or the Help Find My Blower at the top of the page.

GFK-160 Blower Kit
We've had this fireplace for nearly 4 years without a blower. Finally pulled the trigger and purchased over the phone with Jason. Not only did we receive incredible service, but this blower is absolutely amazing and does exactly what they claim it does in their videos. Thank you!!
GZ550 Blower Kit
Dealer wanted 3 times the price, so I picked this up from FireplaceBlowersOnline based on the videos and reviews I had read. Perfect! It's well-made, there's attention to detail and suprisingly effective despite the blower's relatively small size.
Avalon & Lopi Front Mount Replacement Blower
I purchased an old Lopi Freedom stove from a local estate sale and came with the original blower. Blowers were horribly loud and when I removed them, discovered the plastic wheels were badly warped and one would no longer even spin. Swapped them out with these and couldn't be happier. Ball bearings and metal wheels are a nice addition to them being quiet!
FBK-250 Blower Kit
I think it goes without saying that personalized service is becoming a rare commodity these days. But not with this team! My fireplace requires some unique installation steps, which the FireplaceBlowersOnline team was happy to help with. Jason answered my email over the weekend and called me personally the following Monday to confirm I was able to install it myself. Customer for life, thanks guys!
