Atwood RV Furnace Parts

• In typical home environments, the heating system is controlled by one thermostat with an in-built sensor. This provides a single point of control for heating the whole house, but in some older models, keeping certain rooms hotter or colder than others.

• An RV furnace breaks the recreational vehicle into small sections and uses smaller heating units to control temperature in each section. This in turn, reduces costs and minimizes the use of propane when the furnace is running.

• To identify the remote heating sensors in your Atwood RV furnace system, look for the small white or black plastic circles mounted on the walls. One would typically be located in the main cabin of your RV, while other may be in the bedroom or driver’s area. These individual sensors play a big role in determining the RVs temperature. If, for instance, one of located near a window, cold air from outside may trick the sensor into thinking the internal temperature is lower than it really is, and thereby wrongfully activate the furnace.

• Atwood RV furnaces operate on 12V DC power that can either be supplied from a 12 volt DC battery or from an AC to DC converter system. However, there are quite a few Atwood RV furnaces that are specifically designed to operate exclusively on 120 volt AC power supply. Despite, this, they are all tested and designated under the same standards as 12-volt DC models.

If your Atwood RV furnace stops working for any reason, it could be due to the malfunction of any of the furnace parts described below:

• The 851 limit switch - a limit switch is a critical component in RV furnace safety. Limit switches are electromagnetic devices that regulate everything from household appliances to industrial machinery. And for RV furnaces, the devices have two functions: first they won’t allow the fan to turn until the air generated inside your furnace is warm enough and second, they act as a kill switch to the burner should the air temperature around the heat exchanger become too hot. The main reason a limit switch is used on the burner is that when the temperature around the heat exchanger becomes too high, the heat exchanger can crack, allowing toxic by products of combustion into your home. Like all other parts, a limit switch can malfunction and require immediate replacement.

• The Atwood Burner - Atwood gas burners have a high heat efficiency and their fuel costs less, but you must have an ample supply of gas in your RV for them to run smoothly. All the furnaces are engineered for easy maintenance and superior air delivery - all in a compact package to meet today’s demanding space heating needs. Both DC and AC powered versions are available to suit every RV regardless of how it was electrically wired. The Atwood burner 7912-li+8012-li burner is a direct replacement for most burners that comes standard in RV heating spaces but you may need help installing it into your RV.

• Atwood Fenwal DSI board – This Atwood electrical motherboards come ready to be fitted in Atwood burners. They are designed with removable jumpers so you can still use them in instant fire operations in water heaters and refrigerators. They have a diagnostic LED light that identifies any problems and are protected from power surges via the 5 amp surge and fuse protection system. An on-board micro controller is also handy for stable and accurate operation.

• The Blower Motor – This is an exact fit for current RV blower motors should it be necessary to replace the existing one with one that delivery warm air accurate throughout the RV interior. It is a variable speed motor so you can control air to eliminate hot or cold costs. The motor also continues o supply air when running the fan constantly on the “Fan On” setting on your thermostat thereby allowing the filters to capture more dust, mold and pollen particles.
