Hello! Propane heater quit working about 0400 this morning. Woke up to the heater sounding like it was surging with cold air blowing out of the floor vents. My 36FB has a heat pump (electrical strip) in the aft air conditioner unit so between that and the fire place (Eden Pure too) I was able to get it warmed up. Unable to get the suburban propane heater fan motor to stop - other than to pull the fuse.. Called customer service at RW but no return calls yet.

Any troubleshooting recommendations greatly appreciated.. personal recommendations for customer service agents also greatly appreciated!!

Regards,
Tim

Tim, did you switch the tanks over? Are both your tanks empty?I would recommend you check both tanks and try switching over.

John & Sam, checked both tanks - just filled one up last week and the other is still half full.. tried switching over this morning with no luck.. fan just runs with no impact by raising or lowering temperature on thermostat.. except to pull the fuse...

Thank you!

We had a heat problem this past fall. I just could't get it to work. I even requested a new board and limit switch. Was ready to install both and Brian that I had to make sure the line was purged and TO MAKE SURE TO TURN ON THE GAS VERY SWOWLY. Well needless to say it worked and I returned the the unused parts. Good luck.

Toby, many thanks! How did you purge the lines? What's the process? Thanks!

I ran the stove to get the gas to that point. Then unfortunately it's just time till the line clears. It took some time but once it started to work it was great! I think the system times out after three tries, I believe I may have turned off the 12 volt system a couple of times to speed up the process. Something else. The regulators in the RWs are like the ones on your grill, I have take a few hits on it with a hammer handle to make it release the diaphragm. Good luck!

Thanks Jay & Linda - I'll give that a try....

In case it doesn't work does anyone have Brian's email / phone number?

Tim, one more thing, check the wires on the thermistat to be sure all wires are connected and tight also, i would go to the airexcel website and find a local service center under their rv service center as you do not have to go to a crossroads/redwood service center as this is a suburban issue most likely and if the problem is the furnace there will be no charge.

A couple of things to consider:

Turn the heater on and off a several times with about 10 seconds between. This will tell the furnace to prime. Also if it gets anywhere close to zero, LP doesn't want to work because the valves will freeze. You can check this by trying to turn on the stove top. In below zero weather, you can wrap a 12 volt electric pad around the tank to keep the gas flowing.

Good luck
