Fix Honeywell Thermostat Heat Not Working After Battery Change

The problem of the Honeywell thermostats not working after battery change is frequent and very common. If you facing the same. We got this guide for you. This will talk about possible issues that can cause hindrances in Honeywell Thermostats.

Method To Fix Honeywell Thermostat Not Working After Battery Change

The problem you are facing is not new. Honeywell thermostat is quite popular in having issues after battery replacement. The working battery goes for 1 -2 years.

The problem arrives even when you have placed the battery correctly. Yes, this is frustrating, but the problem comes with a solution always. Follow the steps mentioned below and get your comforting thermostat back to work. 

1. Check If You Are Using the Right Battery

If your Honeywell thermostat still does not work, you may be using the wrong batteries. The fresh batteries in your thermostat may not be enough to keep it running. 

Go inside the battery compartment to determine which boost converter your batteries require. For example, 1.5V AA batteries primarily power them. Batteries should be non-rechargeable. 

While getting the necessary batteries, make sure they are of good quality. Poorly made batteries can cause the same concern. Instead, check that the batteries are active and buy high-quality batteries.

2. Replace Battery

If you don’t replace all batteries at once, the thermostat may stop working correctly. Therefore, it’s better to keep new and old ones separate.

For example, replace the batteries in your temperature controller every year with new ones. If the charge levels of the old and new batteries differ, your thermostat may malfunction.

Using both(new and old) batteries simultaneously may result in battery leakage. It results in decreased overall performance.

If your thermostat batteries are low, replace them all for optimal performance. Get strong batteries for your thermostat.

3. Battery Should Be Properly Installed

Sometimes it is neither the quality nor the charges that cause this problem. Instead, it is your placement that is creating the issue.

We often install the batteries without checking the positive-negative in the battery compartment. Instead, look in the box, whether both they should face a similar direction or a different one. You should fulfill the required orientation.

4. Factory Reset

Before moving forward, ensure that you have no problem going for the reset. This will remove configured settings and return the thermostat like it was earlier. It is a straightforward approach and can be helpful in various situations.

Please note: Write down or recall the settings in use beforehand.

Let us look at these steps:

• Step 1 – If appropriate, turn off the thermostat.
• Step 2 – Unlock the door to the battery compartment. Insert a small object into the slot, then flip the chamber door open to release it.
• Step 3 – Remove the battery and insert the new ones. Ensure placing the battery in the wrong manner and on opposite poles.
• Step 4 – Let it stay for 5-10 seconds and remove it again.
• Step 5 – Insert the battery in proper orientation now. Your device display will start working. 
• Step 6- Slide in the cover at the back firmly. Your device has taken control now.
