Furnace Won't Turn On Automatically

Howdy,

We have a 2011 FR Berkshire and live in the Pacific NW. We use our 'Berk all winter, either on short trips or as "surge housing" for when the kids are home from college, guests, etc. It's keep under a nice metal shed, with water, propane, and electric hook ups.

Recently (past week?) the furnace and/or thermostat won't hold a set temperature. It can be set at 65, but be freezing (almost) inside. If I turn the thermostat off and then back on, the furnace kicks in and bring the 'Berk up to temperature and then shuts off. However, it won't turn back on when the temperature drops. It will also turn on if I crank up the temperature (e.g., 70+), but with the same scenario: i.e., comes up to temp, shuts off, and then nothing.

Propane tank is full and I've tried a new full tank, but with the same results.

Any ideas???

Blessings, Dave

Good morning Bama,

Here's a picture of the thermostat. I'm not sure of the furnace model. Where would I find it?

I know for a fact the 5 Button control never had any furnace associated problem.

Try resetting the thermostat.

Quote:
System Reset
A. Turn the On/Off Switch to thee Off position.
B. Simultaneously press the Mode & Zone buttons while switching the On/Off Switch to On. FF should appear in the LCD display until the Mode & Zone buttons are released.

Suburban furnace control boards have been big poblem with failures you are describing. You need to replace the control board with a dinosaur brand control board that is bullet prof. $110.00 or less.

I have put a link to trouble shoot the furnace from the library at the top of this page. Trouble shooting starts on page 23. The trouble shooting section in the manual below is very good and will help you fix your furnace.

Hope this helps Tim
