I had to have the control unit rebuild and am trying to re-install. It wasn't until after I pulled a few wires off the defective part that I realized I should be writing down which part of the circuit they came from. There are 4 single red wires that look the same. Next time I will label them as I take them off. Does anyone have a wiring diagram so I can figure out which red wires go to which post. I assume that 2 are for the lower oven and 2 are for the upper oven, but you know what they say about assuming. Does it matter which post each of the red wires goes on? Thank you .
Answer Hi John. We will explain the wiring from the clock terminal points. Pin numbers and wire colors shown in parentheses ( )
denote lower oven connections. P18-4 and (P26-4) red wire leads to the bake -2000watt element. Then the other red wire from this element feeds a double red connection point on the oven thermal fuse along with the orange wire from the broil 3000watt element. The opposite side of the broil element has a orange wire going to P18-1(P26-2) connection of the clock relay. Right next to the orange /clock connection will be a red wire or a red /white wire that feeds the other side of the upper thermal fuse part # 9759243. Then you will have a red wire from the terminal block which feeds the relay double line break relay. Then next to it is the clock P24-5 GRY wire that feeds the blower motor and the neutral feed to the blower motor is a white wire from the neutral terminal block. HINT: I would use a volt/ohm meter part # TJMA-DM1 to assist. you in your diagnosis. Set the meter at Rx1 on the ohms scale. Test the meter and put the two leads together. You are probably reading .01 or - 0 ohms. You should get very close to this when you are tracing the wires from one end to another to see if "this" particular wire is which wire at the other end. If you have a button that selects the Beep"-method use it also(or instead). So as you test the wire it will automatically beep when you are at the correct trace of the wire needed. If your upper oven has a convection fan, it will have a orange wire connected to the clock connection P24-6 point. NOW for the lower elements. The red wire goes to the clock connection that feed s the bake 2000 watt element. Then the other side of the element is a red wire that goes to the thermal fuse also. Then from the clock connection you will have a orange wire feeding the broil element. The other side of the broil elmt. will have a orange wire that goes to the same thermal fuse red wire connection point. Next to it at the clock terminal point it will have a red wire straight from the terminal block L-2 feed. You should have a wiring diagram in the top of the clock controls or under the top in the front. Thank You.
We have a double oven and it will not come on. We have checked the fuses and the burners all check out ok. The interior light comes on so why won't the oven come on? The panel is electronic not the dial type controls.
Answer Hello Beth. First thing to do is turn off the breaker for 10 minutes. Sometimes an electronic controls' microprocessor will come to a point of stalemate. In other words, it needs to be rebooted. This doesn't always do it but about 30% of the time it does. Once this is done, if the issue still exists, I would drop the control panel and unplug the ribbon cable.Now, using a pencil eraser in the direction of the traces, erase across the connections. It is important to go in the same direction as the traces to prevent damage to them. Reconnect the ribbon cable and hook the panel back to the units' front and power it back up. If this corrects the issue, your ready to bake. If not, you're probably looking at replacing the thermal fuse 4451354. You can check to see if there's power getting to the control first. If there is power getting to the control, the control 8302967 has failed. If there isn't power getting to the control, it's the thermal fuse.
Now to answer the question that's probably burning in your mind. If the thermal fuse is blown, how can the interior light come on? You see, we're dealing with a 240Vac unit. If the one 120Vac leg is open, there's still another 120Vac leg available. I hope this information aides in your repair. Have a great day!
