The coleman uses a vermiculite "sponge" in the dome. after you pump it up and start it, there should be a quarter to half dollar area on the dome that gets saturated with fuel. you light this area then open the valve all the way. the entire dome should glow orange.

I have a coleman presidential electric heater in my mobile home. The heating element works but the blower wont turn on. What could it be?


First check your thermostat.. RED wire(power) should be connected to the GREEN wire(fan).... a Multi- Meter should read 24v if you have power. If there's power going to the FAN(Green) Then your looking at a Bad Blower Motor (AND, OR) A bad Capacitor.

Hopefuly it's just a loose wire or bad capacitor,, the motor isnt cheap..

sounds as if the heater coil itself is burnt out. These coils may be repaired if you can get an universial coil repair kit and rewire the heater coil yourself. Since the age of the unit is in question I don't know if it is possible to get a kit for repairs but you never know. I would check an a/c supply house for this kit. Good Luck on your repairs

Pilot wont stay lite


You either have a bad thermocouple or you need to reset the burner control.

Old coleman dome heater wont light


sounds like your feed tube might be partially plugged, or the orifice, you will need to disassemble the unit and clean it, normally a good dose of high pressure air will clear the tubing and orifice, check the tank too to see if you have any de-bree in it, hope that helps.
