Honeywell error code

Honeywell gas valve blinking 4 times

Honeywell error code
Bob Robertson wrote the following:
I had a power outage at my house and coincidentally (?) my water heater pilot light went out. 
My Kenmore water heater is controlled by the Honeywell Gas Valve (part # 9007884), which contains the WV8840 Communication Port. 
 
The water heater wouldn’t re-light, but I noticed that the indicator was blinking four times in succession.
That signaled an error code for a fatal flaw in the water heater gas valve.
The water heater had supposedly over-heated, even though I had never had it set to anything but “low” (120°F) in the 3 years I have had it. 
By the way, the 3 year warranty expired 3 week ago.
 
The manual, and Sears parts department, told me I needed a new control valve at $150. 
That was their only solution.  They said there was no way to re-set the board.

I researched the internet (many hours!) and found a guy that removed the board allowing the capacitors to discharge fully, (just by removing the board). 
I ended up doing this and it worked like magic. 
Gene adds: the valve is disassembled by removing screw at bottom of gas control:

Steps for replacing gas control

Although, the first time I did it, I only let it sit for about a half hour like he did, and I still got the 4 blinks and it wouldn’t light. 
So, I decided to let it sit overnight and that did the trick for me.  When I put it back in it blinked 7 times. I lit the pilot, and the indicator returned to 1 regular blink (the sign of normal function) as the gas flowed to the burner and ignited.
 
There is no need to completely remove the board from the plastic control valve cover.
The board is held in by one “T-15 torx screw” that would be uncommon for most folks. 
Just make sure you label (or cell phone picture) where the wires go, to be able to return them, and then disconnect all the wires.
This will insure that the board will not be getting any electrostatic signals from the water heater. It’s not very complicated, really.
 
The cover on the Water Heater’s gas valve is removed by a single flat head screw at the bottom. And two finger-pressable connectors at the top. 
You don’t have to drain the tank or disconnect any gas lines.  Although, it wouldn’t hurt to turn the gas off at the water heater line by twisting the valve into the horizontal position.
 
I thought you might want to add this info to your “do-it-yourself” site.  It saved me $150. 
Honeywell and Sears/Home Depot/etc. would encourage you to waste the money on a new part.  Thank God for the internet! 
And thanks so much for the clear directions on your website!

Gene adds: Thanks for your contribution, Bob ... a lot of folks read this page since it was posted Jan 2016 ....
Also ... according to the service manual on pg 5 and 21, 4 blinks can mean a failed gas control which Sears confirmed, but it can also be a tripped ECO (energy cut off which trips when temperature of water inside tank exceeds 199°F ) ./... the temperature probe is a thermistor which changes resistance (measured in ohms) when water temperature changes ... the gas control interprets change in resistance as change in water temperature ... however, since the thermistor is electromechanical, then a temperature of 199° could be simulated onto the thermistor by electrical charge from nearby lightning strike .... the lightning could also destroy the gas valve of course .... resource: why you need ground wire .... but if the problem is tripped ECO, then the supposed repair is to turn gas control knob to OFF and wait minimum 5 minutes before re-lighting.

How to replace Honeywell gas control valve

How to replace Honeywell gas control.
1) Unplug wires and disconnect piezo igniter
2) Remove 1 screw. On front bottom below plastic cover is 1 screw located on left side.
3) Remove plastic cover. Tip plastic cover out from bottom, and then pull straight back toward you and cover snaps off. Caution: plastic cover is connected to body with 3-strand yellow-orange-white wire.
4) Disconnect yellow-orange-white wire. Wire is plugged into circuit board on plastic cover. Grasp wire and pull upward to unplug wire from circuit board..
5) Remove valve body from backplate. There are 2 plastic clips that hold valve body to backplate. These are located at bottom on right and left side. Use screwdriver to push 1 clip down while while using another screwdriver to pry valve body outward. Then use screwdriver to push down other clip to release valve body.

Gas valve will NOT leak if the cover is removed.
Circuit boards vary by gas valve model number and circuit board from another heater cannot be 'plugged' into another valve.

Cautions
Do not take apart the gas valve.
If aluminum cover is removed to expose magnets as shown in photo, the gas valve WILL leak.
There are NO replaceable parts inside the gas valve.... picture is for informational purpose only.

Do NOT reuse a gas valve that has been taken apart as shown in this photo.
Do not reuse gas valve from another heater .... each gas valve has a specific model number, and gas valves vary by type of gas, BTU rating, manifold pressure etc.
Circuit boards vary by gas control and cannot be 'plugged' into another valve.
