Why Is My Honeywell Thermostat Blinking?

An air conditioner is a necessity, as we get into the hottest season of the year. Ideally, we want our air conditioners to work without any problems, as the cost of repair can be expensive.. However, there are people who would question why their Honeywell thermostat is blinking? It is one of the most common issues with today’s programmable thermostats.

A programmable thermostat can keep your air conditioning unit running smoothly and efficiently. Moreover, it can also warn you if there’s any problem with your cooling system. When the blinking occurs, it usually displays the ‘Cool On’ message on the digital thermostat. Let’s take a look at some key reasons why this blinking occurs and how to fix it.

Causes of Honeywell Thermostat Blinking

When the ‘Cool On’ message on your digital thermostat flashes, it means there is a technical issue with your cooling system. The reason for blinking could be anything from a power outage to a low battery. Here are some things that can cause Honeywell thermostat blinking.

1) A power outage

One of the most common causes of thermostat blinking is a power outage. When there is no power supply, it may lead to the blinking of your Honeywell thermostat once the compressor restarts when the power returns. During the restarting process, the pressure on the compressor causes blinking.

2) Switching from cooling to heating

Switching from cooling to heating can put pressure on the compressor. As a result, your Honeywell thermostat will blink. The same happens when you switch from heating to cooling.

3) Battery replacement

The Cool On display tends to flash for a while when you replace your batteries. If the problem persists, call in a professional technician to repair the thermostat in case of any further technical issue.

4) Low battery

When your thermostat is low on battery, it may start blinking. However, this usually happens with the older models. Some of the latest Honeywell thermostats feature a separate notification for a low battery.

What To Do If Honeywell Thermostat Keeps Blinking

You need to reset a Honeywell thermostat because it may fix the issue. If your thermostat keeps blinking after a while, here is what you need to do.

• Turn your thermostat off. Wait for 15-20 seconds and turn it back on. It could take up to 10 minutes because your system will automatically restart.
• If the outdoor unit has not started running again, you will need to call a professional technician to diagnose the problem.
