Honeywell Hot Water Heater Status Light Blinking: What the Code Means

Knowing your Honeywell hot water heater status light blinking can help you determine whether your heater is acting up or it’s running normally. The different water heater has their own mechanism and operational specialties.

For Honeywell, however, the status light blinking can notify you whether it’s normal or not. Keep in mind, though, that the light blinking is quite normal. That’s how the heater is supposed to run and work. But pay attention to how many it should blink.

Honeywell Hot Water Heater Status Light Blinking

As it was mentioned before, the Honeywell water heater thermostat blinking can let you know whether the machine is running well or not. The normal heater should have the status light blinking once within 3 seconds. If you see this, you have nothing to worry about because your unit runs normally and well. The Honeywell heater should flash the blinking light once in three seconds, and it is functioning fine.

Different Blinks, Different Problems

However, when your Honeywell heater blinks several times consecutively every three seconds, it means that there are some possible issues. You can tell the possible issues depending on how many blinks or flashes.

For instance, if the heater blinks two times every three seconds, it may mean that the main valve isn’t turned on or there is a low thermopile voltage. If the unit blinks 3 times every three seconds, it may likely mean that it experiences blocked exhaust piping, a (bad) draft pressure switch, or there is a clog within the condensate drainage system.

You should consult your manual to find out what’s wrong. It’s also possible to reach out to the manufacturer through their customer service. But if you want the fastest result, contact the certified and skilled professional in your area to get help.

Honeywell Hot Water Heater Status Light Blinking 7 Times

If your Honeywell heater blinks 7 (consecutive) times within 3 seconds, your heater may likely have electronics failure. In most cases, the status light blinks when there is something wrong with the gas control valve. You should be able to reset the blinking situation by replacing the (gas) valve or repairing the electric problems.

You should:

  • Check the wire connection of the heater (each one of them). It would be even better if you could hire a professional and certified electrician to make sure.
  • In the event the wiring is okay, check the gas control valve.

If your heater has white blinking light, it’s most likely that the unit is in delay mode. Wait for around 5 minutes. Afterward, it should be on cycle again.

It’s always better to hire and consult a certified professional to find out the core issue and deal with it.
