Is this code on the furnace or the actual thermostat display.If on thermostat, look inside front cover and give me complete model.

Customer: replied 1 month ago.
The model of the thermostat is TCONT900AC43UMM. The error code is on the thermostat. There is no place for a code on the furnace but maybe on the inside. The thermostat has a red light which is lite and located on the right top corner. There is no way for me to stop the fan which thinks the furnace is working. However I can shut off the fan by using the electrical breaker. When they installed the furnace, they had a code book which they used for installation but they would not give me a copy of what the codes meant. I will not call them again because they promised the State/Government would give me a $2000 rebate for efficiency. However they did not install the proper condenser and I got screwed after calling them about 20 times. That's why I am asking you for help.

Thanks for that information.The 22 error is a soft lockout due to flame lost or no ignition.

Lets go to furnace. See if we have a pattern flash code on furnace board and give me model on furnace
