Question about Heating & Cooling

The display on my Ampam by Honeywell programmable thermostat displays all 8s. Is it time to get a new thermostat?

Last night, December 2nd, 2014, we had a power outage. Since the power came back on the display has read all 8's. Is this fixable or should I get a new one?

"Funky" displays often indicate a problem with a control or processor. The simplest fix is removing power for a minute or two and trying again.

Doing this will likely erase any time / temperature program in the t-stat, so you should make note of it before attempting.

I'm not familiar with the t-stat you have, but if it is like most - it has a battery or two inside to maintain the program during power outages (and allows programming while in your easy chair). You should remove the battery(s) and remove it from the wall (most will simply pull away when unclipped / disconnected) to completely power down. Wait a moment and reinstall the battery(s) and reinstall to base on the wall.

My Honeywell programmable thermostat's display is blank and I do not have any heat?


The thermostat, depending on the model, normally does not get powered by batteries, they are for backup power. You might be losing 24 volt from the furnace, causing the thermostat to run on batteries.

Hello, first you must verify if you are getting 24 volts to the tstat at the secondary side of the transformer, if not you have a bad transformer. If you are getting 24 volts then check the batteries in the thermostat.

Check for either an in-line fuse in the heating unit or a fuse on the control board also in the heating unit.
