What is the flash code giving you? Watch flashing closely and count the flashes for me.

Customer: replied 6 years ago.

There were at least 5. I can go check.

Expert:  Jason Hvac replied 6 years ago.

Ok let me know what the count is.

No flashes now that the furnace has kicked on.

Expert:  Jason Hvac replied 6 years ago.

Ok turn it off and try again. We need the furnance to fail. If the unit won't fail then I will be checking on you off and on until it does.

Customer: replied 6 years ago.

How do I turn it off? Do I open the bottom door? This happened 2 weeks ago but not again until today.

Expert:  Jason Hvac replied 6 years ago.

No, that will reset power. Just turn off at thermostat and let the unit stop. Turn back on and let us see what happens.

Customer: replied 6 years ago.

I have turned the thermostat off, the furnace continues to run!

Expert:  Jason Hvac replied 6 years ago.

It should run for about 5 minutes then turn off. Let me know if it does not.

Customer: replied 6 years ago.

It did turn off. I have turned it back on and turned the thermostat up. I hear it kicking on. The light was not flashing.

It just kicked off. I checked the light and it is not flashing. Any suggestions?

Expert:  Jason Hvac replied 6 years ago.

So at the moment its working. Is that what you are saying?

Customer: replied 6 years ago.

Yes. It kicked off when it reached the temp set on the thermostat. No blinking light? I hear it now kicking back on.

Expert:  Jason Hvac replied 6 years ago.

Ok, this is the problem the tech is having while he's checking it. It appears to be working. I need it to fail. I'll be waiting.

Customer: replied 6 years ago.

You may wait for a week or so...:)

Expert:  Jason Hvac replied 6 years ago.

Ok, I'll be watching for you. Just remember when the light starts blinking don't take the door off. If you do it will reset it and we don't want that.

Customer: replied 6 years ago.

Okay

Expert:  Jason Hvac replied 6 years ago.

Thanks, I will be watching for you.
