Great aren’t they, these halogen ovens. You buy one because its cheap and before you know it your using it for all sorts of things.
Then the bulb blows
Ok, not so bad, £15 or so on sethe-bay, but to fit it you have to literally disassemble it. But when its in, it works!
Then it keeps tripping the power
After replacing the bulb I thought that would be it for another 12 months but no, after a couple of weeks it started tripping the house mains power.
Took it apart, thought it was my wiring couldn’t see anything wrong. Wrapped another layer of electrical insulation round the wires put it back together, it worked.
Three weeks later it started shorting out again, aaaarrggh. Now I’m losing patience with it. I leave it sitting in the corner of the kitchen sulking, or maybe I was sulking.
Eventually when I was in a better mood I put my voltmeter across the live and earth terminal on the mains plug and yes, it was shorting. Took it apart AGAIN. I kept the meter on the plug and as I was disassembling the oven it would be shorting then not. Something like a bare cable I thought was touching the metal bodywork. But inspecting the cables nothing was amiss.
Thermostat is the Problem
Took the leads of the thermostat and the problem was gone. Hmmm. I put the voltmeter directly on the thermostat and yes the mains connectors were shorting with the earth side. Nothing to take apart so I gave it a good soaking with Cillit Bang to degrease it. Hour later dried it off and the short was gone!
