Hi folks, Woke up to a 62 degree downstairs... Thermostat had power, but when i went to basement no lights (green or red) visible on board. Unit seems to have power as a fan and attached humidifier and air cleaner were running. 5amp fuse seems to be intact based on visual inspection. Any thoughts? Unit is about 13 years old, serviced annually by Trane Tech, and was working like a champ all winter until this morning. Thanks!
