Today I came to Rick and Alice’s Shaganappi home because the thermostat stopped working on Sunday. Upon inspection I found see the prestige thermostat was blank. Because the thermostat gets its power from the furnace, I checked the furnace and found the bottom door of the furnace was not in contact with the safety door switch. The screw was there however it was too small and fell out of the hole leaving the door open. I replaced the screw with a larger screw and the thermostat powered up. I tested the system on fan function and ac modes with no errors. Becuase Clearview was just here doing the annual maintenance on Friday, and Rick is a member with us, there is no charge for today’s visit. Should other issues arise, diagnostics will be required.
