Leaving air temperature sensor lockout. If the duct temp is normal, the sensor is probably faulty and will require replacement.

Why does a CCC2 thermostat continually kick on and off even though the set temperature has been reached?


Double check your batteries in both the outside and inside units changing the outside ones FIRST before you change to reset the inside batteries, IF you have two separate units. If this doesn't help, it could be the control switch/relay for your interior unit. Please go to your browsers information line and type in DOMETIC CORPORATION.COM AND SEARCH FOR YOUR SPECIFIC THERMOSTAT by entering your CCC2 Comfort Control Center 2 information. They should have a help section at this website.
I hope this helps. Check to see if its still under warranty.

Carrier Comfort Zone 2 flashing E2


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

My Heat will not work on my upstairs unit. I am getting an E2 error code on my carrier thermostat. what does that mean?


the e2 code on a carrier comfort zone thermostat is indicitive of the external safety sensors which are located on your units ductwork in the attic. the e2 code are the hpt/ and lat sensor codes. the hpt is the heat pump temperature sensor and the lat is the leaving air temperature sensor. you can pull off the cover of the panel and behind it will actually give you all the fault codes associated with you carrier tsat.each sensor has a certain ohm rating and if its out of the range it will fail. now as to the reasons for failure, the indoor coil could be dirty, filters dirty, refrigerant charge incorrect.
