I recently wired a double oven with isolator switch but when both ovens on it trips after couple of minutes and the top oven is pretty noisy also any solutions. (i.e) could i have wired incorrectly or is the wrong isolator switch installed etc thanks
Re: recently wired a double oven with isolator switch
Hi, there's definitely a electrical problem.
First, use the bottom oven only for about 15 minutes and check if it doesn't trip.
Second, use just the grill (top oven) for about 15 minutes and check if it doesn't trip.
The reason is sometimes grill elements are corroded and only trip after a few minutes.
Also, if both ovens work ok on their own, then it could be your fuse box not strong enough, or the isolator switch fuse be only 13amp. If your oven is more than 3Kw (check the label on the door for info) then you need a 30amp fuse to hold when both ovens are on.

Kitchen aid is made by Whirlpool. There is a very good chance the then thermal fuse on the back of the oven has tripped. Whirlpools are very prone to this fuse tripping after a clean cycle. The noisy fan is just that a noisy fan it will probably need replacing. I have replace a couple of them over the years. When you pull the oven out to replace the thermal fuse replace the fan motor at the same tiome.
The clue will be when the rcd trips out. If everything is switched off on the cooker with the exception of the clock when you power it up and then it trips out, it could be in the wiring to the oven from the control switch and or the wiring in the oven. The only way you are going to find this is to take the oven out of the housing and test the wiring, isolating components until you find the problem.
Sounds to me to me like a direct short. Hot wire in unit could be touching part of unit. Oven switch if it has one or main board could be shorted. Oven will have to be pulled to check. Slimm possibility weak breaker.
Blower mtr would be a good start will it sit there until you turn on the power toggle switch.You could isolate the blwer mtr by un wiring directly at mtr.Beware there is a few wires in the junction one set of those wires are for the centrifugal switch(ie the fan has to be runnin for the oven to lite)
Make certain that the heating element is properly seated WHEN THE OVEN IS COLD! When you put "current" through wires and heating elements, they vibrate. Zip tie the wires together outside the oven cavity.
It is more than likely the oven element, as it gets
hotter the insulation in the element is breaking down and causing the trip to operate..
Remove the panel at the rear of the oven and you will see the element there, undo the screws and pull the element towards you, carefully, detach the 2 wires and remove the element.
Be careful not to lose the 2 wires behind the oven rear.
Replace with new element.
