Jenn Air Electric Oven not heating on first use
« on: January 23, 2009, 03:55:38 PM »
We just installed a new Jenn Air 30" electric wall oven. We have it wired to a 220/30 amp breaker. When we first turned it on, the panel was working fine, so we decided to test it by heating it to 350. Well after 45 minutes, the temp was only showing as going up to 107 on the panel. We checked and it is getting power, and it never displayed an error code.

Any ideas? We have a service man coming out in 5 days, but I want to make sure that we aren't doing something stupid.

I  would be sure you wired it correctly.  It sounds like you don't have it wired correctly.   The clock can come on with half the power, but not the elements.    Tom  www.applianceeducator.com

Could you let me know what the correct wiring would be? It has 4 wires coming out of the oven (red, black, white & ground). I have run a 4 wire (10 awg) from my box and connected them all to their corresponding colors with the ground to ground. Is this not correct? Thanks!

The red and the black wires on the new oven go to the 240 circuit. The white wire is a Neutral wire and must have a dedicated Neutral line to it. The green is a ground and can go on a bare ground wire. You must have 3 conductor wire coming to the unit.

If you connected the white wire to a hot lead, you have damaged the control relay board and they will not cover it under warranty..

Thanks so much for your help. It turns out that they way the breaker was in the box, we only had 2 110v's going to it not one 220v. I fixed it and it is working perfectly now. :)

I knew you had to have a power problem.   Good Job.    Tom  www.applianceeducator.com
