Customer has a 3 year old American Standard gas furnace, she said that her furnace and thermostat were fried and not working. She had an electrician come by and inspect it, but he wasn't able to do anything. Upon investigation, I found that the thermostat has failed due to a power surge that hit the home. I also found that the fuse on the control board was blown and the contactor at the condenser was fried along with wiring. I replaced thermostat, contactor, and fuse/wiring and tested all modes of operation. All components are within manufacturers specifications and system fully operational. Recommend annual maintenance and power surge protector for either home or equipment.
