How to Fix Honeywell Thermostat Heat Not Working? (2023)


Reset Honeywell Thermostat

I turned on my Honeywell thermostat on a freezing Sunday morning last winter, but it didn’t provide any warm air as expected.

I was cold all day since I couldn’t get the thermostat to work no matter what I did. It brought back memories of a time when I was having connectivity problems with my Honeywell Thermostat.

I attempted every method suggested in the thermostat manual, but none of them seemed to be effective. As a result, I spent the remainder of the day online, searching for any and all resources I could discover to help me resolve the problem.

Faulty sensors, incorrect installation, tripped circuit breakers, and other factors might cause a Honeywell thermostat to fail to switch on the heating system. Resetting your thermostat may be necessary for certain circumstances.

You may need to reset your thermostat if, for example, it’s chilly outside and you’ve turned up the furnace’s setting, but the home still doesn’t seem to be warming up. It all depends on the kind of thermostat that you have.

Reset your thermostat by following the steps outlined in the following paragraphs. A professional may be needed to check out your HVAC system if you try all of these things and still don’t notice a temperature difference at home. If so, Ambient Edge may assist. Call us at (888) 240-8283, and we’ll be there in a matter of minutes.

A thermostat can malfunction in a number of ways. For example, you may observe that the thermostat’s reset button will trip, leaving it in either “ON” or “OFF” mode for the rest of the day or night.

This is most certainly an electrical problem; therefore, you should leave it to the experts to handle it. In fact, this is a hint that you should get a new thermostat more frequently than not.

You may also be having issues with your thermostat’s programs or keeping it at the temperature you want. To learn how to “reset” your thermostat, go to the following list of options. If everything else fails, you may need to bring in an expert to inspect the situation.

The problem with your Honeywell thermostat not turning on the heat may be resolved by just resetting the thermostat. Continue reading to learn about the other options.

Reset The Thermostat

How To Reset Honeywell Thermostat

When the primary heat source is not functioning, a feature known as EM Heat on the Honeywell Thermostat is engaged to keep the temperature stable.

If that doesn’t resolve the problem, the next action that you should do when your Honeywell thermostat is malfunctioning is to reset your Honeywell Thermostat to its factory settings.

Honeywell has introduced a slew of thermostat models throughout the years, each with its own set of capabilities and features.

There is a simple method for quickly resetting a thermostat powered by batteries. In order to do so, this is how:

  1. Remove the batteries from the thermostat and turn it off.
  2. Wrongly inserted the batteries into each other, with the positive wire facing the negative wire.
  3. Allow 10 seconds to pass before rearranging them.
  4. A new factory default setting will be applied to your thermostat. Make sure your thermostat is set to your regular schedule before you leave.
  5. Batteries aren’t required for all Honeywell thermostats. They’re hooked into the electrical system of the house. Use this helpful guide to learn how to reset non-battery thermostats.

The process by which these models are reset differs from one another. Resetting procedures for several of these models are described in further detail below:

The Honeywell Thermostats 1000, 2000 & 7000 series

Honeywell’s 1000, 2000, and 7000 series thermostats all share the same procedure for resetting their thermostats:

  • Turn off both the thermostat and the circuit breaker at the same time.
  • Remove the thermostat cover and the batteries from the thermostat.
  • The battery should be inserted in the opposite direction of the polarity, i.e., the positive end should be on the negative side and vice versa.
  • Holding the batteries in place for 5-10 seconds, remove them and reinstall them in the right position.
  • Turn on both the thermostat and the circuit breaker at the same time.

That’s all there is to it. Your thermostat has been reset for your convenience.

The Honeywell Thermostats 4000 series

A reset button is included in the 4000 series of computers. The following are the actions that must be taken in order to reset this thermostat:

  • Set the thermostat to a comfortable temperature.
  • Three times press the PROGRAM button.
  • There is a tiny hole where the reset button may be found to the right of the buttons on the thermostat’s front panel. Use a sharp item (such as a toothpick, paperclip, or pin) to insert it into the hole and push the button for about 5 seconds to complete the process.

Your thermostat has been reset at this point.

The Honeywell Thermostats 6000, 7000, 8000 & 9000 series

Among the innovative features included in this line of thermostats are an onboard console with buttons and a touchscreen, among other things. By using these capabilities, you may restore them to their original state. The procedures for resetting each series of thermostats are distinct from one another.

Tripped Circuit Breakers

HVAC systems are equipped with circuit breakers to protect them from overheating and causing damage. If you switch off these circuit breakers, your thermostat will not be able to pump hot air.

If you have installed a Honeywell Thermostat without using a C-wire, you will have a much simpler time opening up your electric panel and getting to the wiring.

Simply opening the electrical panel and checking that the circuit breakers are not tripped can solve any problems with a thermostat that won’t switch on heat or air conditioning.

If this is the case, turn the switch to the ON position.

Reset Honeywell Thermostat.

Ensure the furnace is on and the cover is closed.

Please make sure that your furnace is turned on before you begin using the heat setting on your thermostat. Additionally, make sure that the furnace’s circuit breaker is in the ON position.

There are several instances when the thermostat will not pump heat if the furnace’s lid is left open. When using a thermostat, you should totally shut off your furnace door.

Broken Sensor

A defective temperature sensor in your thermostat will result in insufficient heat being sent to the surrounding area.

Use a thermometer to measure the temperature of the room and then compare that temperature to the temperature shown on your thermostat to see how well your sensor is performing overall.

It is reasonable to presume that the fault resides with the sensor if both temperatures are significantly different from one another. After that, you’ll have to replace the sensor altogether.

Improper Installation

When it comes to incorrect installation, there are two scenarios:

  • In the absence of a professional expert, you have installed the thermostat yourself (either by yourself or a handyman). Mistakes such as poor wiring, misalignment of the thermostat, and other issues may arise in this situation.

While verifying the wire connections, open the thermostat panel and refer to the thermostat handbook. A technician should be consulted in cases when you are unsure of what to do.

  • Installed near a window, an air vent, or any other location where the air is constant. The oncoming wind will have an effect on the temperature measurements in these places.

Because of this, your thermostat will be unable to sufficiently heat or cool your space.

For this problem, move the thermostat to a location where there is little or no breeze so that the thermostat can take reliable temperature data in the future.

Call Honeywell support

When all of the adjustments mentioned earlier fail to resolve the issue, you should contact Honeywell to have a technician come out and inspect your thermostat.

How to Bring the Heat with Honeywell Thermostats?

Other factors that might impair the performance of your Honeywell thermostat include low batteries, dirty filters that can hinder airflow, vents that have been blocked by anything (e.g., wrong settings), and other factors.

Consequently, it is necessary to clean the filters and vents regularly and change the batteries on a regular basis.

Additionally, when a power loss happens, there is a possibility that the day and time settings may be adjusted. The correct working of the thermostat is rendered impossible under such circumstances. I’ve also put up a full tutorial on how to replace Honeywell Thermostat Batteries.

FAQs:

Question

Is there a reset button on a Honeywell thermostat?

When you open the Honeywell 4000 series, you’ll see that it has a reset button hidden within a tiny hole on the front panel that can only be pushed with a sharp object (paper clip, toothpick, etc.).
All other Honeywell thermostats may be reset by removing the batteries or using built-in features and choices.

What happens when the Honeywell thermostat goes blank?

A blank screen on your Honeywell thermostat indicates no power being supplied to it by the wall outlet.
This may be attributable to a variety of factors like dead batteries, tripped circuit breakers, and so on.

What is the recovery mode on the Honeywell thermostat?

Your Honeywell thermostat gradually activates heating or cooling in recovery mode to reach the appropriate temperature.
As a result, the recovery mode functions more like a thermostat warm-up mode.
