My heat has stopped working in the house. The fan still blows but the air temp coming out of the register is house temperature.
I recently installed a hunter touchscreen thermostat controller and wired it up according to directions. The heat has been working for a week since I installed it though.
I cracked open the air handler to inspect it. The 5 amp fuse is still ok. The cfm LED last night was flashing 9 times. This morning the LED is staying on for about 9 sec and turning off for about 2 sec. It will continue this cycle.
Does anyone have any suggestions what the error on the board is telling me?
My air handler is a Trane model# TWE049e13fb1
Thanks so much for all your suggestions in advance.
