Whirlpool Polara Range--Bake, Convect Bake, Broil and Clean--no heat-no error co

[pjgrose]

Bake, Broil, Clean does not work on my oven.  There are no error messages on the top control panel.  It lights up fine.  Both elements look fine and tested fine.  They are receiving current.  My husband and I have run the voltage tester on every part you can imagine.  Everything shows ok except when he tests the electronic control board on the side of the range.  The red, blue and yellow wires showed no reading, but the others in that plug did show a current.  There was a smudged black area around the ground wire port on the electronic control board.  The in-line fuse if fine.  The oven clicks like it is trying to come on but never heats up. Tester showed current getting to the control panel.  It looks like the electronic control board on the side has been replaced before.  In going through the paperwork, it looks like this oven was a return/used.  It was presented to us as a closeout model and new when we purchased it in 2004.  I just discovered a yellow sticker on back of the closeout sign that said used.   Any suggestions on what to replace would be much appreciated.

Hi,

It would be helpful if you could post the model number from the model/serial number tag that located on the range.

Are you using a multimeter to check for voltage or just a lighted voltage tester?

[pjgrose]

Model # GR556LRKC0.  Used a multimeter to test.  Parts I am not sure which or if to replace Control Panel #9782613, or Electronic Control #8523034 or #6610333 (same part manufacturer replaced 3034 with 0333)

[AJ]

When I look up model GR556LRKC0 it calls for control part # 8190770

How did you come up with the other part numbers?

[pjgrose]

Its the same part...my manual is old.

...  They are receiving current. 
... voltage tester on every part you can imagine. 

I think you have current and voltage confused.
They are different ..
Did you test the (3) Thermal Safety Devices ?
(I'm not sure which one is for the Bake / Broil)
# 12, # 17, # 21

Check your DLB relay.  It's the big relay with two red wires.  With the oven on, check for a voltage drop across the terminals.  0 VAC is good, 240 VAC is bad. 

[pjgrose]

Where is the DLB relay located?  We could not identify it on the parts list in the manual. We are new to this, but trying to fix my range to prepare a rehersal dinner for my son's wedding next Friday night.  Thanks for your patience.

If I am right it is the black square box located on the manager board in front of the range.  It read 241  ACV on our digital multimeter.  Can this be replaced without replacing the whole board? Part #9782613 aka #8190770  which is #10 on control panel parts in manual.

If you have soldering skills, you can try just replacing the relay.  There should be some numbers on the relay. I can usually find them at mouser.com.  Another option is to have the board rebuilt at fixyourboard.com or corecentricsolutions.com

Luckily my husband knows someone who has those skills.  Thanks so much for your patience and help.  I will post how it turns out, hopefully in time for the wedding, so I don't have to buy a new range.

Hi pjgrose. I've never worked on one of these Polara ranges or even seen one. It's an interesting concept. How do you like it? Do you use the cooling feature often?

[pjgrose]

It was the relay on the control panel board!  I spent $11.00 and it works great.  Soooo much better than buying a new board at around $300 or a refurbished one for over $100.  I cannot tell you how much I appreciate your help.  I am going to tell all of my friends on facebook about your website.  I just wish I had found you guys in time to make the rehearsal dinner for my son's wedding.  It was not fun baking 4  3-layer cakes one layer at a time in a tiny toaster oven.

MajorApp, I do like my polara range.  I do not often use the programming b/c we have some pretty bad power surges here and I have a fear of leaving it set when I am not at home.  I have used it to set a turkey on Thanksgiving, so I didn't have to get up so early to start it.  Also use it on Christmas morning.  Have a nice toasty breakfast casserole ready when we get up.  Its great for parties too.  Can use the fridge on it to keep extra drinks cool, or food trays that won't fit in the fridg will certainly fit in this oven.  My only complaint is that the control panel is in the front and moisture gets to them if something boils over.  It was probably that or the power surges that caused my problem.  Overall it is an awesome concept.

I would love to see a video of the relay replacement. That would be cool.
