Customer Question
Hi. ***** ***** here...

Hi. ***** ***** here. Our heat will not turn off even though the thermostat is set to 71 and the heat in the house is 78!!! I've tried to turn the heat OFF and the system still stayed on.

Contractor's Assistant: Thanks. Can you give me any more details about your issue?

This is the second time this has happened in the past week. It is now 79 is our house and the heat will not turn off. What do you need know exactly?

HVAC Technician: airheatman, HVAC Technician replied 2 years ago

I expected so. Your problem is a stuck sequencer in the air handler. Is that something you are comfortable replacing

Ask Your Own HVAC Question
Customer reply replied 2 years ago
Where is the sequencer located?
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

It will be top panel of air handler .Give me air handler model and I can be a bit more specific.

Goodman model ssz 140301ag
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

That is outdoor. Indoor is what stays running

Ask Your Own HVAC Question
Customer reply replied 2 years ago
Ok. It is Honeywell but I don't know the model #. Where can I find it?
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

LOL. Indoor is most likely Goodman also. It will be in closet attic or basement.Air handler is where the air is drawn in and recirculated through ducts

Ask Your Own HVAC Question
Customer reply replied 2 years ago
Ok. I cannot get into the crawl space at this time. Can you tell me what should do after I get the model number?
Customer reply replied 2 years ago
I guess we are done then?
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

If you would like to continue when you can get to air handler or have someone there who can, we can troubleshoot, but most likely we will find the sequencer needs to be replaced.
