SOURCE: Smell Coming From Intertherm Furnace

It could be several things.

The most alarming being a cracked heat exchanger allowing the exhaust fumes to enter the living space.

Exhaust fumes that contain carbon monoxide.

I HIGHLY RECCOMEND that you purchase carbon monoxide detectors, and/or check the batteries in any you might already have.

Carbon monoxide can be deadly at high concentrations.

It could be burning wires, but would smell like burnt rubber.

It could be mold/mildew but would smell musty like dirty socks.

It could be a build up of dust oil etc on the heat exchanger, but that is usually only smelled when it is started up for the first time in months.

Make sure the filters are clean. Dirty filters can cause overheating of the heat exchanger and sometimes cause smells.

This is one of those times I will recommend you have a professional look at your unit.
Specifically the heat exchanger to look for cracks.

A pro will know where to look, where the usual stress points are etc.

SOURCE: i have a intertherm gas furnace mgha-056abfc-01 the pilot light will not stay light.

If it's not the limit switch, perhaps the thermocouple or gas valve is defective.
Was there a gas outage?

Where is the flame sensor on Intertherm MGHA-070abfc-01?


There is no flame sensor per se, unless it has an ignition type pilot. Only temperature activated switches employed.

The limit switch to the left of fan switch is "Nordyne" part #626259. This switch is rated at140 degrees. When the temperature inside firebox exceeds 140 degrees, switch "opens" removing power from the secondary of 24vac xfmr.

The fan switch to the right of the limit switch is "Nordyne" part #626337. This switch closes when firebox temp reaches 115 degrees. Opens at 70 degrees.

At the top to the left of fan is a smaller limit switch, which is a secondary safety switch. The increased temperature within the heat exchanger box activates this switch. It is wired in series with the thermostat wiring.

Hope this info helps.
