Question about Carrier Air Conditioners

1 Answer

I have Carrier Comfort Zone 2 on a York system. Everything has worked fine. After recent lightning strike, the controller is not responding correctly. It flashes E1 alternating with the current temp. No matter what the programming, it seems to start cooling when the house gets to 84-85 degrees inside and then stays on continually until it hits the programmed 76-77. How do I test to see if zone panel or thermostats need replacing?

the e2 error on your thermostat is a problem with the return temp sensor on your system, the only thing you can really do is call a company and replace it, you can't bypass it or remove it cause the system wont run properly

You didn't get a Carrier tech. Carrier technicians only work on commercial equipment. Residential applicaitions, installation and service of Carrier residential units are done by dealers. They are not carrier owned but get buy the product at discount get training and get to show our logo. You can't fix the boards, they have to be replaced. It sounds like you have a Gen II VVT system. You can get the part via Totaline stores or a distributor. You will need to know how to readdress the other controllers to operate correctly. Use WWW.Carrier.com.

This .pdf file may be of help to you:

Perhaps you could get some help from Carrier Support here:
http://www.residential.carrier.com/support/index.shtml
I noticed they have an option of talking to an engineer, and perhaps they could explain how to reset or set the unit.
Hope this helps.

Unit/control panel completely dead


Check your circuit breaker, "off" and "on" the breaker it my be tripped off. If it wont work may be some fuse blown in the control, or the control itself may be defective.
