I have a kitchenaid kesc307 range/oven with an oven that doesnt heat up. Digital keypad doesnt light up but upper burners work and indicator lights work.  Any suggestions on what to look for ? I'm hoping its something simple such as a loose wire or bad fuse.  Anyone seen this before? Thanks!

Model KESC307HBS6

Serial IML3599391

Type 30P

 

The terminal block for the incoming power looks like the oven requires 3phase wiring.. Is this normal? There is a L1 terminal, an L2 terminal and an "N" terminal in the middle. It looks like the old stove neutral wire was wired to the ground wire is this right? I had the oven wired with just the L1 and L2 wires hooked up and the burners operate, tried connecting the "N" wire to the ground and oven still doesnt come on. Inline fuse is good and both thermal switches meter ok. Any  ideas?

line 1 and line 2 on the outside terminals on the block, neutral/common go in the middle terminal, this is normal hook-up.  this is not 3 phase....just a normal double 40 or 50 amp breaker system.  If the top burners work but the oven does not something is stopping the oven from coming on. Will try to pull up the tech sheet..

It's not three phase power; it's single-phase, two-pole pole-- 120v wrt neutral on each of two hot lines, 240v line to line.

You need to verify you have 120v wrt neutral on each of the lines. Also, verify that the ERC (display board) is getting 120v.

Do you have a three-prong or a four-prong power cord?

what terminals on the display board should read 120V?

Power supply voltage: should have 120v (wrt neutral) at both P6 and P7; your power supply neutral is the white wire on P1-1.

I have a 3 wire plug. just black, white and ground. No Neutral wire.... the neutral for the old stove looks like it was just tied to the  ground wire.

Here's where it gets tricky. Your oven has two control boards: a microcomputer and a display/input board. We need to see if the display/input board is getting voltage. The tech sheet doesn't say what it is or where to look, but it's typically something in the range of 5 to 14 volts DC (watch your meter settings). This will help us determine whether or not the display board is getting its supply voltage to light up the display.

I think I may have found the problem. The 120V/24V transformer on the board isnt outputting 24V. I have 120Volts going into the transformer but nothing going out. Any idea where i can find jus the transformer? there are no manufacturer markings on it of course...... it has model #'s but a web search came up with nothing..

It seems kitchenaid went to great lengths to make it difficult to find board level parts for these control boards. I may have to buy the complete board.:X  I've tried all the major suppliers and no one can find this transformer. Does anyone have any suggestions or know of a contact at kitchenaid or whirlpool????

Ok, I installed a new contol board and the display is now working however  4 buttons on the touchpad are not working (1,4,7 and convect full meal).  Tried reseating the plugs but no change. This is a new stove (I bought it as a scratch and dent) so its never actually seen any use.... Is it really possible the touchpad is bad also?
