The heat or air dosent turn on, when i switch the switch to fan on from auto it dosent come on either. I changed the batteries in the thermostat and checked the breakers at the panel and on the furnace itself, tripped them and turned them back on.

Hello Wendy,

You didn't say what kind of system you have, so we'll assume you have central heating and air conditioning.

There are a few things you can do to keep air moving in the house with your central system. Depending on the brand of system you have, you can turn the heat/cool switch on the thermostat to "off" and turn the fan auto/on switch to "on." This will disable cooling and heating but allow the fan to run continuously.

You can turn the thermostat up to a temperature far above what you would normally use in summer and turn the auto/off fan switch to on. This will force the fan to run continuously. The cooling will still work when the temperature in the building exceeds the higher set point.

These steps will work on most systems but if you have one of the new "NEST" or other internet-connected temperature control systems, you can refer to the operating instructions to see what your options might be.

Note that leaving the fan on all the time will result in higher electrical costs, more wear and tear and you may have to clean or change the furnace filter more often.

You might be better served by purchasing a free-standing floor type "tower" fan and placing it in the room you are in most frequently.

You could also use (or install) ceiling fans.

Could be a bad blower motor resistor,mounted by the blower.

If your thermostat is being used with an electric heating system and the fan does not start in heating mode on auto; remove the thermostat from the subcase on the wall and check for a switch on the back of the thermostat. A lot of electronic thermostats have a switch on the back that says electric/heat pump and gas/oil. If you have electric heat or heat pump you need to switch it to this side. Usually this is set at the factory for gas/ oil. Gas/oil furnaces have built in means of bringing on the fan and electric/ heat pumps are brought on by the thermostat.

At your thermostat ,
Set switch to heat, turn up temp switch.
Fan should be set to auto. Wait up to 5 mins to be surethat somthing is wrong. If your fan comes on without heat. Check gas valve or if heat pump check main a/c breaker. If elect heat or any of above dosn't work.
Call a service company. If your in Pensacola. Look up Absolute Heating and Air Conditioning.

Most T-Stats have a On / Auto on a forced air system. On means the fan will run all the time even if it is not calling for heat. Auto only runs when calling for heat. Does the fan turn off in the auto mode at all? To test it...BE SURE THE FAN IS IN THE AUTO MODE ON THE T-STAT... Turn the thermostat all the way down and keep it there for appox 15 mins. If it is wired properly and the fan limit is set properly the fan should turn off. If it doesn't it is not the thermostat were the problem lies.

Most forced air units have a fan / high limit switch. There is a setting on the switch for the fan to turn on and a setting for the fan to turn off or it has a setting and a differental switch for it to turn off/on. Example - the fan comes on when the temp in the heat exchanger reaches 110 degrees F and will shut down at 95 degrees F after the thermostat is satified...this would hav a differental of 15 degrees F. It may be set to low and the fan continues to run long after all of the heat has been removed from the heat exchanger. This in turn will cause cool air to be coming out of the registers.

The model of T-stat you gave comes up as a discontinued model on Honeywell's web site, but it looks to be a manual stat that type of stat would have to be wired with a summer winter switch with electric heat, allowing it to turn on the fan with a call for heat. If yours is a programmable T-stat you would need to select electric heat or in the installers set up change the default setting for fan from unit controls fan in heat to thermostat controls fan.

Well, if need be, turn the breaker off. Turn it on when you need heat. Sounds like the fan relay is sticking or something if that sort. Is the tstat fan selector on auto?

The fans are set to delay for 60-90 seconds to remove all heat from the heat exchanger/heater elements.

If the fan runs any longer than 3-4 minutes after the Emergency Heat shuts off, you may have a bad sequencing relay in the air handler.

Have you confirmed that the thermostat is programmed correctly?

Did the thermostat ever control the temperature of the house properly?

When you indicate "kick", are you talking about flipping the Auto-On switch back and forth? The Auto-On switch only controls the fan, and no heating or cooling (Auto - fan runs on call for heat or cool, On- fan runs all the time.).

If "kick" means making the heating work, and if you have the same problem for making the cooling work, chances are good you have bad thermostat.

If the problem only occurs with the heating, and cooling works fine, then the problem could be in the controller board of the furnace, assuming you have a more recent (1990's or newer) furnace.

Try this, disconnect the fanwire (green) on the furnace, if it shuts off then the hot wire from the thermostat is touching the green wire or bad thermostat. Thank-you-very-much!
