No bake or broils

[Georges Applianc]

The display seems to work . It shows that it is suppose to be heating on both the bake mode and the broil mode, but the elements don't even get warm. Both elements have continuity.

Model 790.95321301

Assuming that there is voltage coming to the control I believe the control is bad. So if you get 240V from the L1 to L2 the control is bad. Note the control could still light up on 110V so just because it is lit doesn’t mean it is getting voltage.


This is also assuming there isn't a loose connection between the board and the elements.

I think this is going to be the same control I had a lot of trouble with. I had four in a row were one of the solder joints on the back of the board was burnt. On three of them I was able to repair the solder joint with my trusty solder gun. You will have to separate the control from the plastic frame to see if there is a burnt joint.

On all four it was the same joint was bad but I couldn’t tell you which one it was but it will be obvious once you get the frame out. In any case it won’t hurt to look.

Change the ERC.

Ryan post some pictures of the repair dude. Very interesting.

I wish I could but it has been a while back and as far as know they are still using the controls.

It was odd that I saw four of the same solder joint bad within a month time and haven’t seen it since. This other one of the four was burnt so bad I couldn’t even think about repairing so I had to replace it.

I am not in the habit of repairing bad control boards but it is nothing wrong with repairing a bad solder joint from time to time.

Ryan you were right on it was a bad solder connection. Thanks for the help.

SO!! It was a bad ERC!!

I am glad I could help you find the problem.

Now you have to decide if you want to change the control board or fix the solder joint. If you have and know how to use a solder gun you can repair this board and save money. However if the solder joint is bunt so bad that it has damaged the surrounding circuits you will have to replace the board. Also if you do not know how to properly fix this it will not last long.

Clean the joint as well as you can, and then place the board on a flat surface. Get your gun good and hot then heat the joint that is to be repaired. When everything is nice and hot touch the end of the soldering iron briefly with the solder. The solder should run down onto the joint and make a pretty joint.

Replace the board if…

1.   If you are uncomfortable doing this repair.
2.   If the joint is burnt too badly.
3.   If repairing the joint doesn’t correct the problem.
4.   If the joint you repair ever fails again.
5.   Once the repair is done check and make sure that the oven will cycle. If it    continues to heat (gets too hot) the relay on the board is bad so replace the board.

I believe that sometimes when these boards are manufactured a solder joint may not get enough solder or something to that nature. 

A lot of techs will recommend replacing the board no matter what. I don’t necessarily disagree (it is not bad advice) but I have been successful doing this type of repair many times.

I hope this helps!

Ryan,
Acutally it was a easy fix.The ssolder joint just didn't have hardly any solder on it, no burning nothing. I got my soldering iron usedsome good electrical solder and made the connection. Thanks again for aiming me in the right direction.

Good Deal!!! Glad to help

If you would have taken a photo of that fix that would have been sweet.
