My heat pump wasn't working and I checked the thermostat and it was flashing heat on. I called someone who said the fuse was blown and replaced it to do troubleshooting. They came to the conclusion it was the defrost board which they replaced. They also replaced my thermostat. This occurred in the spring of last year. Early December the same thing happens my thermostat is flashing and I put it in Emergency Heat until a tech can come look at it. They did some troubleshooting and replaced the thermostat with another. Not sure what they did but it ran fine until this week! Same thing the thermostat began flashing heat on after it ran fine for over a month!
