Oven not heating. I have a KitchenAid Pro Line Dual Fuel Range

SOURCE: Frigidaire electric range

is there voltage going to the erc (electronic range control)?

Hello all with this oven not working problem!!! I had this happen and I found exactly what causes this to fail. The circuits operate in the following manner... The oven is controlled by a double pole single throw heavy relay (wired as a single pole single throw or simple off/on relay) that supplies power to 2 other relays.. The oven relay is a double pole double throw relay (6 contacts 12 volt coil, ) it is normally open circuit, that is when the main relay turns on the power goes to the oven relay but no further. The other sie of the oven relay is wired to a second relay connected to the broil element that is normally open circuit with the other side of the DPDT relay going to Leg 2 120 volts. So in normal off mode the broiler is connected to the one side of the relay, common is connected to Leg 2 and the other side of the relay is connected to the other side of the oven relay.
SO when you call for the Bake Oven element, the power goes through the main relay to the oven relay, the oven relay clicks and now connects the oven relay to the set of contacts on the broiler relay that is connected to Leg 2- now the oven turns on. When you ask for broil the oven relay turns off and the broiler relay tirns on connecting the broiler to leg 2 (bypassing the oven relay.
I know its long winded but basically to operate the oven the power goes through 3 relays where the broiler only uses 2 of the relays (not the oven relay) Kinda dumb way to do it I suppose BUT the idea is to never have a situation where the oven and broiler can be on at the same time.
Heres what happened with my oven.. the broiler relay failed (broke internally) and the common contact shorted across both of the other terminals momentarily turning on BOTH elements, the sudden inrush of current literally exploded the output contact on the main relay and vaporizing the lead, trace and solder joint.
It was a mess... badly burned.. I found a new relay (omron) to replace the main relay.. but the other 2 were Omrons that I could not find replacements for (12 volt coils is the issue) So I did find some potter brumfield relays that were rated 10 amps per pole so I wired these externally from the timer board (ran wires to them) (doubled up so each relay was using both sides in parallel so it can handle 20 amps) The elements only use about 8 amps each anyways this worked great and since the new relays are on spade terminals with quick disconnects, are easy to swap out of they fry again (doubtful) Its a forgone conclusion these timers are ready to fry at any time and I can almost guarantee the WILL blow.. the relays arent very heavy duty at all... I would not buy another of these.. pretty weak control.. expecially these small relays.
Good luck in your repair.. a new timer was 300 my repair was 50 and WILL NOT fail like theirs did.
Cheers
Dave

SOURCE: Power Failure results in no oven or digital display.

The low voltage has ruined the CCU (clock) YOu will need to replace it. You can order the part via model # on sears.com

It sounds like you are missing part of your input voltage.

I would take a voltage reading at the receptacle and confirm you are reading 220-240VAC. Some homes have the 220 service receptacles wired up with two 120 volt breakers to make up your 220 service. If your home is configured this way, you may have one of the breakers tripped. Or, the receptacle itself may be bad. If you confirm you have the correct voltage at the receptacle, your power cord may be bad.

The reason the clock and display will still appear to work is because the clock only uses 110-120VAC and is tapped off the source voltage. The surface burners and the oven heating elements, however, require the full 220 service.

If you are confused by this explanation, please post back and let me know. Hopefully, this is a problem that will not require any parts or a service call. If the power cord is bad, you can purchase a replacement at any hardware store. I hope this information is helpful.

Testimonial: "I will definitely check both the 120v wires in receptacle feeding power to the stove. The breaker in the house breaker box is a single 60amp breaker. "
