What does it mean when water heater says thermopile voltage low?
What does it mean when water heater says thermopile voltage low?
If the thermopile does not generate the correct voltage, the heater may fail to provide you hot water. So, this is what the thermopile voltage low error means. The error means the thermocouples in the collection cannot generate enough current to power the control panel that we mentioned.
What causes low voltage on a water heater?
When it comes to your hot water heater, the pilot light heats up the thermopile. As this occurs, they produce a small voltage of electricity that passes over to the gas control valve. A pilot light can go out. When this happens, there is no electricity, so it shuts down the gas control valve until the light is relit.
What happens when the pilot light goes out on a hot water heater?
What should the voltage be on a whirlpool water heater?
If power is present, use a volt meter and confirm that the voltage is correct. The rating plate on the water heater specifies the required voltage. Usually, this is 240 V. If power is not present or the voltage is wrong, a qualified electrician may be needed to fix your electrical problem.
How to troubleshoot a whirlpool energy smart water heater?
The Installation Instructions have a Diagnostic Code Chart and a Troubleshooting Chart you can use to identify and correct problems. If the LED light on the Control Board is not on, check to make sure the unit is getting electrical power. You can check for power with a simple “circuit tester” or volt meter.

How often does Honeywell water heater have low thermopile voltage?
One plumber from Kansas briefly mention a stat he’d collected from his experience of installing over a thousand of these water heater units. About 1 in 125 units will have this Thermopile Voltage Low error. Ok, so that’s less than 1%. That must be an acceptable quality threshold for Honeywell.
Is there a problem with my Honeywell water heater?
Update June 2019: For those looking for a solution to this problem, we ended up un-installing our new water heater, hauling the entire tank back to Home Depot, and switching it out. The second one worked just fine.
