How do you check a bad gas control valve on a water heater?
Andrew Davis How do you check a bad gas control valve on a water heater?
To check the pilot control, follow the lighting instruction on the water heater. Do not try to light the pilot if you smell gas. Press the pilot button down and light the pilot. If the pilot lit but will not stay lit when the pilot button is released the water heater thermocouple could be the problem.

Why does my Honeywell water heater stop heating?
If you have a Honeywell gas valve on your water heater, and you find you have no hot water, this may be the answer to your problem and the easy fix. The Honeywell gas valve went into “High Temperature Shutdown” mode. When this happens, the gas valve closes, extinguishes the pilot light and your water heater stops heating water.
Are there any problems with Honeywell gas valves?
There’s a common problem with some Honeywell gas valves that operate some water heaters. I have a Reliance brand, 40 gallon, natural gas water heater with a Honeywell gas valve, model WV8840B1109, and it has this common problem.
What should the voltage be on a Honeywell water heater?
I would check the voltage on the gas valve first then. It should be 12 vac. If the voltage is correct on the gas valve then replace the thermopile. If it is less then the gas valve has failed and is not opening all the way. Attachment: 2015-04-21_141433_honeywell_control.pdf
