Check your "over temperature module" for both top and bottom zones when the alarm is active, there is a bank of LED's on the bottom of this module. Monitor it to find out if the same zone keeps activating the alarm, if so check your TC for that zone. Problem could be the TC or the module.

One of the air temp sensors by the blower is bad. Unplug them and check each to find the defective one.
