Hi,
GBD307PRB01 Whirlpool DBL wall oven - The unit is about 4 years old and for some reason the lower oven elements will not heat up. The control panel shows the lower over temp and heat is on, but both elements are cold and will not heat up. The upper oven works fine. What can I do to fix this?

Please help.

Thanks

Ron

Here are your parts
Replacement parts for WHIRLPOOL GBD307PRB01 30" Built - in Electric Double Oven Convection - Upper Self - Clean (gold Line) | AppliancePartsPros.com

Here is the tech sheet
http://www.servicematters.com/d...0Sheet%20-%208302068.pdf

If the temperature sensor readout is OK then it is probably the thermal fuse. See the tech sheet lower oven wiring. I believe this is Item 29 in Section 1 of the parts.

If the sensor readout is high it could be an open sensor.
Also could be a control board relay is shot.

Thank you for your response. I have a few more questions. I do have a VOM tester, but not sure how to read a closed circuit for the oven shutdown thermal fuse. I am sure that I must shut off the circuit breaker on the fuse panel before testing. And it states to (Short the upper double line break relay red wire terminals fastons) not sure what this means?

Thanks again for your help.

Neither do I. I would imagine they are measuring it from the control board but do not understand why they want to short out the relay.

Unplug the unit.
Remove at the wires from the thermal fuse and measure it, should be 0 ohms.
Removing at least one wire from it ensures that you do not read an alternate/parallel circuit path.

You could also check it at the control board.
Unplug the unit and measure:
From P26-4/Red to RedWhite should be approximately 28 ohms
From P26-2/Orange to RedWhite should be approximately 19 ohms

If both are open (infinite ohms) either the fuse is gone ot the RedWhite wire is broken/open.
