Atwood Furnace Limit Switch Location

It will be located at the top of the panel.

Atwood furnace limit switch location.

Furnace is running but not firing up so either the delay switch is broken or the circuit board. The fan blade assembly on the combustion chamber side stays in it s cage. The larger assembly needs to be removed to access the motor so it can also be removed. Figure out which model of furnace you have be sure you have the correct model number the parts are different for the different models.

9 times out of 10 it is the delay switch. The limit switch is a simple temperature controlled switch. Remove the cover by lifting it upwards or pulling it off to reveal the body of the switch and two metal arms. I tried firing up my furnace in my rv it sounded good at first until it never ignited.

If the temperature of the combustion chamber exceeds the preset limit the switch will open and disrupt the flow of current to the circuit board in effect shutting down the main burner. This is part 1 in a sears of videos for the operation diagnosis and repair of an atwood furnace. It s function is to monitor the combustion chamber heat level. The limit switch is behind the blower assembly.

So i did some research read manuals and narrowed it down to the sail. Remove the face of the fan shroud then the blade assemblies and then the motor. The limit switch is not hard to find or replace.
