I was called to a home to repair a thermostat that was stuck closed, overheated, and had blown a thermal fuse. Upon arrival, I found that the thermostat was not responding to the thermostat's controls, and the temperature in the home was rising rapidly. I diagnosed the issue as a faulty thermostat and replaced it with a new one. I also checked the electrical wiring and connections to ensure they were secure and in good condition. After completing the repairs, I tested the thermostat to ensure it was working properly and that the temperature in the home was back to normal. The homeowner was very pleased with the work I had done and thanked me for my prompt and efficient service.
