Question about Jenn-Air WW27430P Stainless Steel Electric Double Oven

1 Answer

I have a double oven. Model WW27430. The top oven will not heat. The bottom is fine. I was told that is was the relay board. which I replaced and I am still having the same problem. Could both heating elements go out at the same time?

    well, as I continue to troubleshoot, I see that it can not be the baking element. (from the bottom of the oven) I switched the bottem oven bottom element with the top oven bottom element and it still did not work. so maybe its about the broiling element?

    does that mean if its the "temp cut out", the entire oven needs to be pulled out to repair? also, the only relay board I see is in the top. I see no other relay board. there is another board but not like the relay board. where would the other board be located?

Looking at the schematic I see 2 possibilities:

1. I think the most likely cause is a failed "limit switch" aka "thermal fuse" aka "temperature cutout". For each oven there is a limit switch that feeds power to both elements. So the upper limit switch is probably tripped which would kill power to the upper bake and broil elements. The limit switch is usually located on the back wall of the oven cavity.

2. There are a relay board for each oven. Be sure you changed the right one.

Whirlpool gold double oven model #gbd307pdb. upper oven lower heating element burned out. replace lower element. it does not get hot. upper element heats up. control board works. is this the thermos


You will have to see if there is power to the element. It is possible that the relay contacts burned when the element burned out. There is a fusable link but this would shut down both the top and bottom elements. If the relay is burned out the control board will need replacing or rebuilding.

Frigidaire double convection wall ovens, model GLEB30T9DSA ... The top oven will not heat, both the bottom element and the broiler.....


I have the Frigidaire PLEB30S8CCA single wall oven. About 3 months ago the baking element appeared to have gone out. We replaced it, but still didn't work. We ended up sending our control board off to a company named Corecentric. They fixed the problem and returned it to us. The oven has worked perfectly ever since. I searched extensively for a new one, but no one sold them anymore. I found Corecentric on Ebay. They were able to confirm over the phone that it was more than likely a control board issue. It cost about $130. My husband was able to do it himself by taking a couple before px and using them when reassembling it.

Dacor bottom oven not heating


I have a DACOR double electric oven model ECD230SCH. the top oven lower element went out 1 and 1/2 years ago, but the top element broiler works. Yesterday the bottom oven did the same thing- bottom element not working along with convection. Pulled off doors and cut breaker. Checked thermal switch on top off oven- closed good. Pull out element and Ohm'ed out- good. Now pulled over and out oven top panel to get to the control boards. Found a nice set of schematics for the over control boards and electronics. Sat down and pin-pointed both relays that supply power to upper and lower oven "lower" heating elements. these are on 2 different boards- upper over relays on bigger board on the left with the transformer. Lower oven on the right smaller board. Hardest pain in the rear was just getting the little plastic stand offs to push back through the board to get it off. Finally got it off and inspected board. Low and behold the relay I pin-pointed had a burn/open connection on the solder joint. Re-soldered tested oven and lower oven lower heat element works now! Went to the next board and got that off and same exact problem on the rely for the top oven lower element. Re-solder and test- good!! Put everything together and ran over to 350 on top and lower and back to normal. Wife very happy she did not have to pay a repair man big bucks to swap out the control boards- would have had to replace both.

I have a degree in electronic technology so as a technician for many years did low and high voltage component level repairs. But pretty easy and you can visually see the open solder joint on the back of the board at the relay leg.

Frigidaire wall over model number CGEB30S8AB1 is not heating. It is just the bottom bake element. I tried to replace the element but it is still not working. I can hear the relay clicking but it will...


I had this problem a year ago (both elements worked in top oven but only broil element worked in the lower of the dual ovens). I swapped elements around but the problem was still the bottom element bottom oven.

So I called the repairman. He replaced the relay board (Part #AP2127301) for the lower oven, and it worked again. Yippee.

But now a year later, I have the exact same problem. Lower element on lower oven is not working (Frigidaire you have got to be kidding)!

However this time I decided to take a look at the relay board myself, to at least save the expense of the repairman. I looked closely at the board and thought I saw a cold solder joint on relay K4. But just to be safe I touched up all the connections on all the relays with flux and a soldering iron.

Works perfectly again !!

Please if you try this, disconnect the power first. In fact if I had to tell you that, then just call somebody.

I just found out my baking oven doesn't work and I hear the fan for the convection roast, but no heat. I had the appliance man out and he said that I need a relay board! Big bucks and they don't make this model anymore. Moreover, the microwave and warming drawer work fine. This is ridiculous!

GE double oven - bottem will not heat, top oven fine


I had a similar problem. Solved mine by resetting the manual reset thermal switch. The switch for the top oven is located behind the control panal which can be removed easily by taking out three screws then lifting up an leaning out. The switch has a red reset button, just push it in till it clicks.

For safety, SWITCH THE BREAKER OFF WHILE YOU DO THIS!!!

The lower oven switch is located behind the vent grill between the two ovens.

GE should be ashamed of hiding this feature-it isn't mentioned in the manual. I discovered it on a schematic hidden behind the control panal.

Good Luck, DVS1936

Fridgiaire Gallery series Model GLEB30T8CBA lower elements dont work


I replaced the relay board for the top oven (the one with the transformer) and it works properly now. My issue was only for the top oven so you probably have to replace both relay boards since both ovens have only the top element working.

318022002 is the part number for the relay board with transformer
318022001 is the part number for the relay board without transformer

Yes the one without the transformer is more expensive for some reason.

The boards are on the top of the oven, I was able to pull out the oven about 75% of the way out of the cabinet and easily get to the boards. Just unplugged the connections and plugged them into the new board.

To get the oven out there are two small screws that go into brackets inside the top oven door. Highly recommend taking the doors off the oven to pull it out, much easier to work with.

NOTE: On my old board I noticed one solder joint that was burned out and I since I already had the new board I just replaced but you might want to check that first and see if just a solder fix gets you working again before you spend $$ on a new board.
