Dead blower motors, damaged evaporator coils, and dirty pipes can keep your honeywell thermostat from working properly.

Honeywell thermostat says aux heat on but not working. We have a heatpump system with a ng furnace as the aux/backup controlled by a honeywell 8320 thermostat. There are some settings in the thermostat that need to be looked at. Initially, we examine what may go incorrect with the thermometer.

To begin fixing your heating, continue to the air flow section. We detail a few of these issues below, followed by diagnosing approaches and restoration recommendations to help you address them. Hvac access door/furnace door is open;

Check that switch on thermostat is set to heat or auto. The thermostat is set so that emergency heat is the one that we use for heat. Therefore, if it’s below 40 outside and the auxiliary heat isn’t working, then your heat pump will just blow lukewarm or cool air.

If temperature setting is higher than current temperature, and display says heat on, contact your heating and air conditioning contractor honeywell enviracaire elite he225a thermostat troubleshooting If the temperature does not pick up within the first few minutes, many of the new honeywell models will prompt the aux heat setting. If your heating is not working, it's probably due to issues with the following:

Why is my heating not working? I have central air with heat pump and an oil burning furnace for radiator heat in my home. Heatpump works flawlessly for 10 months out of the year but once the outside temp gets below 30 the heatpump turns off and the aux doesn't start.

If no wire is present then you don’t have aux heat which means that the heat pump balance. It may seem like it isn’t much you can do when your honeywell thermostat says the auxiliary heat is on or any other model thermostat. So it relies on an auxiliary (aux) heat coil (like the ones you see in a toaster) or a furnace to heat your home.

Check the mode and temperature. The aux heat indicator on your thermostat lets you know when this is happening. The heat setting operates the heat pump.

This mainly happens after a power outage. Check the wire in the aux/w2 connector. You can try to turn up the set temperature significantly, just to test the system.

The ignition on the furnace was replaced last week, and ever since the interior. Make sure hvac access doors, as well as the furnace door, are shut. Typically you would put in a heat pump or some other form of emergency heating option here.

The thermostat clicks but nothing happens. Yes, the battery should be able to keep the clock settings right but it. The installation manual that came with the thermostat should give you instructions on these settings.

You may need to make some additional changes to your home to keep the auxiliary heat from coming on. Well you have to catch it doing the defrost cycle not really acting up when it does this it is suppose to do this if the copper in the unit is frosting over. You may also notice your honeywell thermostat has a blinking screen when the heat is on, or that your thermostat seems to be powering on and off more than it should.

Honeywell thermostat says heat on but no heat. A faulty thermostat might cause this, poor installation, failed circuits. If you feel like the heat isn’t turning on timely and that the thermostat isn’t reaching the temperature level, you could check for the following:

If your digital thermostat isn't working so your heat or ac isn't turning on. This might be because your thermostat is actually on the wrong setting. It might be a very simple solution.

Inspect the pilot igniter for debris that can prevent it from heating and clean it. Turning your thermostat to “heat” came with an unexpected “aux” function appearing. If the temperatures are extremely frigid outside, even this may be too much for your unit.

The main signifier that your honeywell thermostat is reading the wrong temperature is that your house is colder than you have set it to be. A weak battery, dirty air filter, or a problem with the compressor can make a honeywell thermostat say the heat is on when there is no heat. In order for the furnace to start running, you need to set the thermostat for a temperature that requires the air to be warmed up.

A less likely, but possible, cause of no heat on a heat pump system is a bad thermostat. If i select the em heat setting then the furnace will work properly. Auxiliary heat on a honeywell thermostat is the place where you would wire in some form of secondary heat source.

We have seen instances on newer electronic thermostats where the relay outputs fail to energize the auxiliary heaters even though the thermostat display shows that aux heat is activated. For those homeowners who never had an issue with their old thermostats but are suddenly experiencing this phenomenon, it may have to do with the specific model of thermostat that you purchased and installed. If the heating/cooling system does not respond to your honeywell thermostat, there might be a problem with the selected mode.

Your thermostat determines when the auxiliary heat gets energized. A technician will need to repair the auxiliary heat. While it is running you see the aux show on the t'stat?is this thermostat newly installed and if so did anyone ever go into the advanced settings and set it up for your heat pump system?

If your heat still isn't working find a rel. When you are activating and syncing up a furnace to the thermostat, you would not use this option on the thermostat itself. If you honeywell thermostat is not working despite saying it's currently heating or cooling then try out the following troubleshooting steps.
