got a oven and of late its not heating up to what it should, anyone good one them ?

Sounds like the thermostate

that a big job ?

no, just google your cooker make and model and try to get service manual, it should not cost to much for thermostate

If it's staying on low flame, it could be the fsd.

i will ask steve when he gets in & let you know

it might be mercury vapour switch

I think the jangal shaft has failed, which is stopping the thingy majig from working.

If your jangal shaft has failed you need a marawitcher, otherwise its down to the wotdjemacallit.

or maybe the oojimaflip?
