Question about Intertherm Air Conditioners

1 Answer

I have a mobile home furnace Intertherm #1378. The pilot light is on, but the burner will not light. The thermostat clicks on and everything seems to be running properly, but there is no flame. Last year I had the motor replaced and the relay switch. What could be wrong? Is there a gas valve that is not opening properly.

First make sure that the gas valve is in the on position. There is a spring load diaphragm that will stick when not in use over time, When the t-stat clicks on for heat tap the valve with a hammer LIGHTLY. If it doesn't come on replace the valve.

Intertherm gas furnace in mobile home..igniter comes on then nothing tries to fire byrners but nothing


by igniter I assume you mean the thermocoupler. are you turning the control button to run after you light the pilot light? Normally when those furnaces quit it is the thermocoupler that has quit. Get a new one and leave it in the furnace compartment as a spare.

Intertherm furnace M1BG wont fire


Make sure the gas valve is turned to the ON position after you had it in PILOT position. Also check the thermostat low voltage wiring @ furnace...jumper the Red & White wires to bypass the thermostat temporarily. Make sure there is 24 volts on you low voltage circuit.

Heater is not igniting


see this causes and fix it. God bless you
f there is no heat, check the electrical service panel for a burned fuse or tripped breaker. Relight the pilot light (see below). If there is not enough heat, adjust the burner air shutter (see below); and clean the burner ports (see below).
If the pilot light does not light or does not stay lit, clean the pilot orifice carefully with a toothpick, test the thermocouple and replace it if it is faulty (see below).
If the flame flickers, adjust the pilot (see below).
If there is an exploding sound when the burner ignites, adjust the pilot to a higher setting and clean the pilot orifice and the burner ports.
If the burner takes more than a few seconds to ignite, clean the pilot orifice and adjust the pilot light.
If the burner flame is uneven, clean the burner ports. If the burner flame is very yellow, clean the burner; open vents in the furnace room to provide more air; adjust the burner air shutter.
If the furnace makes a rumbling noise when the burners are off, clean the burner and adjust the burner air shutter.
If the air is too dry, wash or replace the evaporator pad if you have a humidifier; test the humidistat; and adjust the water-level float to raise the water level.
If some rooms are too cool and others too warm, the distribution system may require balancing. Refer to the Forced-Air Distribution Fix-It Guide .

How do I light an Intertherm furnace Model Number MG 068A?


Hello, if the Furnace is a standing pilot then turn the knob on the gas valve to pilot, you will hear a hissing sound then use a match or a lighter to light it at the thermoouple. Hold the knob on pilot for about 30 seconds and then turn the knob to gas and burners should ignite.

I have an early 80's mobile home with an "intertherm gas atmospheric furnace" pilot light is lit but can't get the furnace to "fire". Seems as though the limit control is stuck open. ...


If your pilot light is lit then I would first check your thermostat. Make sure it is on heat setting and fan is on auto, turn stat up to where it should be calling for heat. If you don't get burner to light remove front cover from thermostat and see if it has a mercury switch, if it does move temperature selector up and down and see if you can see a spark in mercury switch vial. If y ou cannot see a spark remove screws that attach t-stat to base.Remove carefully and disconnect wires that go to r and w terminals on stat base. Temporarily connect these two wires together. This should make burner light if you have power to thermostat. If burner does light disconnect wires and replace thermostat. Also if you have a volt meter check across these two wires and see if you have power there. Should be around 24 volts a.c. If your thermostat has a fan on setting try that. If fan runs you know you have power to furnace The gas valve needs 24 volts to operate and inside the electric control box in furnace there is a transformer to step down 110-120 supply voltage to 24 volts. If transformer is working you should be able to hear a low buzz or humming sound. You can also check across gas valve terminals when t-stat is set for heat, you should read about 24 volts. If you have 24 volts to gas valve and it is not opening then you need to replace gas valve. The main purpose of the limit switches is to turn blower on when temperature in heat exchanger reaches fan on temp,shut off blower after burner shuts off and heat in heat exchanger reaches fan off temperature, and limit if temperature exceedes set point without blower coming on. I hope this helps you. Thanks

Rheem gas furnace pilot lights, but no burners or fan


If the burners do not fully ignite, the sensor will shut the furnace down. The lack of sufficient burner flame is a gas valve or gas pressure problem within the valve.
Replacing the gas valve with the original one may get you going. I surely suggest a professional service company for safety reasons and a thorough inspection. A 20 year old furnace is past it's normal life span.

We have a Intertherm MAC 1378 gas furnace in out mobile home and it has shut off on us. There is still gas coming in, we checked the meter outside to be sure. But when we try to reignite the pilot light it...


Check to make sure the roof vent is not covered over with snow.
Very deep snow can block the intake to the furnace. You may need a ladder and a broom (or shovel) to clear the snow.
Hope this helps.

My gas furnace that came with the Mobile Home I just purchased will not ignite the Pilot Lite. All valves from tank open, followed instructions. No Spark


Try lighting all other gas appliances first. On a new setup air in the lines between the tank and the furnace takes time to bleed out before the gas reaches the pilot light.
