Question and Answers

Q:

Whirlpool Gold double electric oven, Model # GBD277PDQ09 & serial # XR3011191. Electrical storm but no nearby lightning. Malfunction when power back up.

A:

You could have a problem with the house circuit breakers or the power supply that is provided to the oven. Check the circuit breakers to see if those are tripped. If you find no problems with the power supply that is provided to the oven, then you could have a blown thermal fuse in that power supply wire going to the control board in the console. The first image below shows a wiring diagram with the power supply for the control board and the transformer traced in red and blue. That thermal fuse in that circuit could prevent the transformer from getting power. The second image shows the location of components in the oven. The 3rd, 4th and 5th images show access information for the components in that oven. You can shut off the house circuit breaker for the oven to completely disconnect electrical power and check that thermal fuse for the control. Here is a link for a brief repair video that shows how to check for continuity through a thermal fuse: Thermal Fuse Testing . That thermal fuse in your oven console may be different than the one shown in the access images. If it is blown, you can replace it with part 4451042. You can order that part from the Sears PartsDirect website. Here is a direct link for that part: Fuse .

If that thermal fuse is okay, then you could have a bad transformer. You will probably need to check live voltage going to that transformer. NOTE: Use extreme caution when checking live voltage in that oven. Wear proper protective equipment (electrical safety gloves and safety goggles). Shut off the circuit breakers to the oven as soon as live testing is completed. You should only check this live voltage if you are completely confident in your technical ability to safely measure it . If you need to have a service technician check that voltage, you can schedule service through this link: Sears Home Services .

You should measure 120 volts AC going to that transformer through the red wires. If that transformer is getting that 120 volt power then you should measure low voltage (probably 24 volts DC) out of those blue wires. I don't have the exact specification on that low voltage out of that transformer. It could be 24 volts AC instead of DC. If you are getting no voltage at all then that transformer will need to be replaced. You can order parts from the Sears PartsDirect website. The part number for that transformer is 9760587. Here is a direct link for that part: Transformer .

If that transformer is not getting power then you could have a wiring failure or a blown thermal fuse as described above.

These tips may help you resolve this oven problem on your own. If you need more help, reply with additional details.

Here are the 4th and 5th images. Be sure that you shut off the house circuit breakers for the oven before accessing internal components.

I added a resistance check for that transformer in the image below. Be sure that you have the house circuit breakers shut off to completely disconnect electrical power when checking that resistance. This may help you further test that low voltage transformer. Your details indicate that the transformer is getting the 120 volt AC supply power. Check that low voltage output in a DC and AC setting on your meter. I do not have a specification on whether it is AC or DC supply voltage to the control board. The technical information just indicates that it should be around 24 or 25 volts. If you need more help, let us know.

Since the control board (part W10406070) is getting the low voltage power from the transformer, it should power up the display. The next step in troubleshooting this problem is to replace that control board. I added a link for that part below this response. Replacing that control board may fix your problem. Hopefully you do not have any further damage or failures due to that power outage. If you need more help, reply with additional details.

I checked with the manufacturer regarding that substituted control board. The manufacturer indicates that it is a valid substitute part that should work in your oven. The connections may be in different locations. There should be no problems connecting the original wires. You can use the wiring diagram shown above as a guide if necessary. If you decide to replace that component yourself and you need help with the installation, let us know.
