LP wall heater blower motor doesn't turn on

I'm sure it ran a few days ago before we ran out of fuel. I restarted the pilot and have good flame, but the blower motor won't start. could this be faulty thermostat? some safety thing?

    Empire wall heater: model number DU36-156: the fuel fires up when it gets that chilly in the house, and shuts off when it gets warm enough, so I'm sure the thermostat works to some degree. but the heater fan doesn't kick on. isn't that run by a couple more wires that go to the thermostat? I find out today that they have like regular extension cord looking wires running to the thermostat, and not the regular low voltage wires. could this cause the problem? thank's to all; Gregory

Does the heater burner come on? If the burner comes on then the problem is not in the t-stat. What is the model# & serial # and brand of heater. If you turn off power to unit and turn t-stat off, then turn unit back on then go to t-stat turn it up to temp. setting you want. Then you should be able to see heater gas valve opened and fired. If it has fired up then it will run for a couple of minutes before the fan will run. If you have anymore ? about the heater operation let me know.

    wires going to t-stat will be fine . The fan is ran by the control board inside the heater. If you have a volt meter you could check the motor to see if it has power coming from the control board. You can also check continuity to see if motor is ok.

Either you have a pressure problem due to a frozen regulator on your LP tank or the air intake for the burner is clogged with dust/lint and/or pet hair.

Let's start with the frozen regulator on the tank first. Soak a bath towel in hot water, ring it out and quickly wrap it around the regulator inside the top of bonnet (lid) of the tank. Leave it in place until it becomes cool. Go make inside, light the pilot, holding the pilot Control Knob for at least 1 minute. After 1 minute, ease off the Control Knob and turn the knob to ON. Watch the flames to see if they are higher than before and it continues to burn normally. If it does, you've solved the problem.

Since this freezing may reoccur (especially if you're in an extremely cold environment now). Go back out to the tank and wrap a dry towel around the regulator, in an effort to stop it from refreezing. If your tank is in a shaded area and doesn't get much sun throughout the day, it could refreeze again.

As far as the air intake on the burner is concerned. You will have to remove the front half of the cabinet of the heater to access it. But, before we get into that, do the other recommended solution first. If that doesn't solve the problem, get back to me and I'll give you the instructions on how to clean the heater.

Good luck ... Rich

Too much gas pressure. Are you sure that this is a LP heater and not a Natural gas heater? Is the regulator you have rated under 1/2 pound pressure? Try to throttle down the shutoff on the tank to see if pilot gets better. If so, you have a pressure issue. Gas you adjust the pilot gas valve?

Williams debonair wall heater + pilot light problems


THE flame from the pilot should shoot past the thermo-couple and heat this up and make a small amount of mili- amps to prove the pilot light is lit. ..So if the flame doesn,t go past the thermo-couple it won, make mili-amps or its tme to change out the thermo-couple, They only cost lest than $8:00 and you can change it!

PILOT LIGHTING BUT CANNOT TURN ON WITOUT IT GOING OUT


change the gas valve, if the thermocoupling works and the piliot stays lit then it has to be the gas valve check to make sure the screen is clear also,, you said it's propane, check to make sure it is all the way turned on, and has the right pressure it might have a bad regulator on it, but will let other things in the house run good luck

Pilot light goes out when turning on the thermostat


Check your thermocoupling to make sure that it is sensing flame. You can tell if it is good or bad by the white on the tip of the flame sensor. The other problem would be a blocked or closed flue pipe. Make sure that the cap is not smashed down on the pipe on your roof
