Whirlpool Double Oven Faint Clock and Temperature

Whirlpool Double Oven Faint Clock and Temperature could be caused by corroded wire nuts at the terminal block. Continue reading for details!

A very nice lady from Houston sent us the oven controller from her Whirlpool RBD275 built-in double oven. We determined the control board had failed, rebuilt it and returned it to her. Mrs Nice sent back the control board a week later with a note saying the display was very dim. We powered it up on our test bench and the display looked great. Needless to say, we were a bit confused by this conundrum. After discussions with Mrs Nice, we narrowed the symptoms to, “I can read the blue clock okay (but not great), and I can see the temperature until I start to bake. Once I start to bake, the display dims even more. I can’t read the temperature display after a few seconds of starting bake.”

We determined that her entire display was dimming when the voltage to the control board dropped. So, long story short … the wire nut connections on the main power feed to her oven were corroded … a few seconds after pressing “start” the bake relay kicked on and drew high current causing the control board voltage to droop.

On the bench we hooked up a Variac (variable transformer) to test at proper and then compare to drooped voltage. You can see in the pictures that at full voltage display looks great (lower)  but with the line voltage dropped to 91V (upper) you can still read clock but the orange digits are almost gone. It’s a characteristic of the display technology (vacuum flourescent display – VFD).

Difference between low voltage & high voltage

It’s a good quick visual to see failing breakers and oxidized wire nuts (at least once they’re degraded enough to add about 0.5 ohms of resistance to power feed).
