Programmable thermostat went blank
Asked Aug 29, 2006, 09:50 AM
Our thermostat (which has been serving solely as a thermometer since the last time we used the heat in the spring) blanked out yesterday afternoon. I checked the inside temp. during the day, then last evening the face was completely blank. It is completely unresponsive to any button pushing. I checked for batteries, but it appears to be wired to the house electrical system. The tech at BatteriesPlus saw no battery in the diagram and digital photo I made. What might be the problem? It's only 3 years old. Thank you for any help you might offer.
