Furnace blower

[Jim and Pat]

The furnace blower in my 2006 LaPalma will not start. Any suggestions?

It could be a fuse, the thermostat, the control box in the AC unit, the reset button on the furnace, or a bad motor, or a mouse stuck in it, or...........
More info is needed.

Can you hear anything at all when the furnace fan SHOULD come on? On one fifth wheel we had the fan was a plastic "squirrel cage" type fan and it completely disintegrated. We happened to be in the RV and heard the clattering, otherwise we would have had no idea what happened because except for the noise when it blew up, there was nothing that seemed wrong except no air blowing. The motor was running so we could hear that, just no air coming out.

Ultimately we replaced it with an aluminum fan that was still working well when we traded that RV in.

And, lots of other potential causes as others have listed.

Welcome to RVforums from Ely, Iowa. I would check the thermostat and fuses first.

Just went through this. Check the circuit breaker/on-off switch located in the heater unit. Make sure batteries are fully charged as my 2002 Diplomat has a cut off to save battery power. There is a delay when the thermostat is engaged (I jumped my fan to make sure it was functional). Check to see if any electrical connectors have come loose. Once fan was engaged I diagnosed that my sail switch was only giving intermittent power and replaced it. Furnace now reliably works.
