Coleman Mach Thermostat Wont Restart Furnace

[eusefullone]

Thanks in advance for any help.... have a 2025 Alliance with 3 Coleman Mach thermostats.

The issue is I can get the thermostat to start the furnace AND it will go off as it should when reaching the Set To Temp.

PROBLEM is it will NOT restart after the room cools down below the Set To Temp....regardless of the range below the Set To Temp.
(e.g. set to temp is 72 degrees and the room cools to 65 it still will not start the furnace unless I manually turn it off and then back to heat, and only then will it fire back up)

Is this a bad thermostat or a bad relay switch in the Control Board? If the control board for the furnace, where is that board physically located? Thanks again for some quick help!

Update: The compressor on the brand new Furrion 12V fridge was shot. So, gladly Furrion issues a new one and Alliance covered the install costs with the warranty. End result, the new fridge is working perfectly and hopefully will for a long time. Thanks again for your help.

Hi folks, only a comment that I am confused by this post.
It starts out asking for assistance on a Coleman Mach Thermostat and ends stating that the Furrion 12v fridge compressor was shot and covered under warranty.
None the less I am glad your fridge is working perfectly and hoping you resolved your t-stat issue.

Travel Safe!
