Customer Question
I have a intertherm...

I have a intertherm gas furnace mgha-056abfc-01 that is short cycling. Runs for about 45 secs and blower shuts off with burner still on. Blower was replaced about 6 years ago along with fan switch and limit switch.

Contractor's Assistant: Did you double-check the thermostat? And what about the pilot light?

I swapped the thermostat last night. The pilot light is fine, The burners are working.

Contractor's Assistant: Do you plan on doing the work yourself?

I usualy do if I can find the problem. Checked continuity on flame roll over limit switch and its good.

Contractor's Assistant: Anything else we should know to help you best?

Not that I know of Its a mobile home if that matters

Hello, try setting the fan and limit switch 20 degrees higher, as a brief test only. If that changes the short cycling situation, tell me what the settings are.

We can go from there.

I am asking for a refund this was a joke and waste of time and money!!!!!
HVAC Technician: Phil, Mechanical Engineer replied 5 months ago

Hello, I can put in for a refund if you wish.

However we handle many questions at a time and there is usually a delay while we do research and type up answers... both take time... there are no pat answers without that research, pulling the manuals and etc.
