Heater problems

Having heater problems with a Suburban model NT-16SE. When I turn the heater on it just hums for a period of time, dimming the lights in the trailer even though generator is running. Then eventually stopping. Blower never turns on or no heat. Really appreciate any help you can give! Tried a number of times and managed to blow the fuse for the heater.

    Having the same issues with my Atwood.. Suspect sized blower.. Tried turning the blower manually, it turns but... Not freely.. Will be doing more diagnosis later this week... Thankfully. not a problem at this time (Did not need heat last night).

    You will have to remove the furnace and inspect the fan motor. If there is no obstruction you need a motor.

    Pull it down and check for a wasp nest in the blower wheel, very common.

    sounds like heater motor is frozen tight, it that is it then you need a new motor, I paid $100 for my last one
