I have a maple chase Thermostat control in my home. It was flashing low battery, I changed the battery,I had also noticed the temp had dropped to 63,(at all times I keep it set at 68 in the fall in winter months). Since I have changed the battery I cannot get the temp back up above 60. It will only blow cool air. Can anyone please help me. I have checked the breaker and its fine and there is no pilot light on this system. Please any suggestions

Read the faq section

Then repost the question with details, i.e. : type of furnace

Fault code if any etc.

It is a comfortmaker by RPJ II. I don't have any fault codes.

Go to
https://www.askmehelpdesk.com/heating-air-conditioning/heating-cooling-maintenance-repair-troubleshooting-frequently-asked-questions-58313.html There is an easy procedure for checking if it is the furnace or thermostat. If it is the furnace, go to the sequence of operations. Once you have some idea what the trouble is, you can post back if you need help with specific details.

If it won't heat and no fault codes, it may be the thermostat.
