Honeywell WV8840B1109 temp control valve on water heater. Status light @ 4 blinks between 3 seconds indicating "high temperature shutdown" even though lighting pilot with water cold. .


II have exactly the same problem: Honeywell WV8840B1109 temp
control valve on water heater. Pilot is on, but the burner won't
no matter how high I turn the temperature knob. Status light blink
4, which by the controller is "high temperature shutdown" and has
nothing to do with the problem. The real problem is that the
computer chip in the controller has gone bad. Problem is solved by
changing a new gas control valve/thermostat. The old Honeywell
control valve uses pure mechanical stuff and was very reliable,
almost never has a problem. I don't understand why they switch to
this new electrical one which use the tiny voltage generated by
the thermopile to run, easy to break, because of the electric
chips, and is more expensive. The only reason I can think of is
that they want to get more money from our pocket.

Then re-post question with exact model number and include what you are operating so expert can access and read manual alongside you.

If you have some other device, then post the brand and model number, and include what voltage, and what you are controlling for best possible solution.

I have an A. O. Smith Model FPSH 40-261 hot water heater. It won't heat water. there is a green light on the control flashing. What does it mean?


AO Smith uses the Honeywell ICON gas valve with green indicator light.
Some models use White Rodgers Intellivent with a row of indicator lights.

The gas control blinks the error code:
