Have a Jeff double oven, about 5 years old. 20 mins to get

Customer Question

Hi have a Jeff double oven , about 5 years old. Ames 20 mins to get to 160c and the light goes out before it gets there. I've had an engineer in twice. He tells me it's the thermostat and I've had 2 replacements and the light still goes out too early and it still takes over 20 mins to get hot. I have my own oven thermometer in. What else can be wrong?
JA: Is your oven gas or electric?
Customer: Electric
JA: How long has this been going on with your oven? What have you tried so far?
Customer: A few months. Called in a good engineer and had two thermostat replacements.also after he'd gone I couldn't push the oven button in, but to call him back he would have to take the whole oven out
JA: Anything else we should know to help you best?
Customer: Just feel I can't trust it. It does get to the right temperature eventually but takes ages just to get o 160c

which oven thermometer is trustworthy? my top oven was set at 160c and my thermometer showed it had gone up to 200C
Expert:  KevinWhiteJA replied 7 months ago.

The elements and fan work fine ?

Did he check the element with a multimeter ?

I mean if any of those were not open circuit why was it replaced?

Please check this IMAGE #1

(part#206 and part#209 are temperature regulators), did he replace both of them ?

Part#249 is temperature limiter, did he test that part with a multimeter ?

Also check this IMAGE #2

If the above parts from Image#1 appear fine then test part#503 for continuity.

After you have tested the above parts and they are all fine/replaced earlier then check this IMAGE#3 (part#804 will need replacement).

Let me know how it goes.
