Furnace Not Working Right? How To Check Your Thermostat

If you are having an issue with your furnace, the first thing that you need to do is start by evaluating the state of your thermostat. Oftentimes, what seems like a big issue with your furnace is actually an issue with your thermostat. Here are a few things you need to check with your thermostat when your furnace seems to be acting out.

Check the Heat/Cool Setting

The first thing you need to do is check the settings. Make sure that the thermostat is set to heat instead of cool. This switch can easily get tripped when you are making other adjustments to the thermostat. Having the thermostat set to cool instead of heat is going to produce widely different results for your home.

Look at the Program Time

Second, you need to look at the time setting on the thermostat if you have a programmable thermostat. Make sure that the thermostat is set to the right time of day. When the a.m. and p.m. settings get mixed up, you may feel like your furnace isn't working when really it is just doing the wrong settings for the actual time of day. Also, make sure that you are programming the right settings at the right time of day. Little programming issues can make you think your furnace isn't working right.

Change the Battery

Third, if your thermostat has a battery, it may be time to replace it. A battery that is low on juice, but not fully dead, could impact the accuracy and performance of your thermostat.

Clean the Thermostat

Fourth, you need to clean the thermostat. Wipe down the outside of the thermostat. Then take off the thermostat cover. It may click off or you may have to use screws to accomplish this. When you take off the outside of the cover, use a can of air to clean away and remove dust and debris. Put the cover back on, and make sure that thermostat is firmly attached to the wall. If there are any loose wires, secure them.

Adjust the Temperature Settings

If you are worried that your furnace isn't turning on when it should, look at the room temperature and then set the thermostat to five degrees above the room temperature. That should be enough of a difference to trigger your furnace to come on.

If your furnace still doesn't come on, put in the temperature into the thermostat and press the "hold' button to trigger your furnace. If you need to do that, your thermostat may have a bug in its system that isn't allowing the programmable side to work right.

Before looking into furnace repairs, like those from A & A Service Company, make sure that everything is set-up and working right on the thermostat end of things. If you have any more questions, though, don't hesitate to ask the professionals.
