When i use the switch to turn it off nothing happens the furnace will work and the fan works it

HI my name is Robert...

Normally when this occurs and you have to turn it OFF with the breaker you have a failed relay on the circuit board inside the AC unit. If the relay was stuck it would prevent the AC unit from shutting down...... Robert

I tried to give you a call as well, it did not go through, if you would like me to call still please let me know and I can send you the request. IF this is satisfactory then please feel free to select a rating at the top of the page... I would replace the circuit board inside the AC unit.... Robert

How do I call Robert?
Expert:  Robert replied 10 months ago.

the company offers a phone service and there is an extra charge for that, I am pretty confident the issue is the circuit board inside the AC unit, when the relay fails on the board you will have the issue you are having..... I can help you in this format or send you the phone request if you like??? Please keep in mind I only get credit when you select a rating at the top of the page... Robert
