Fitted two stats to the top oven but customer keeps complaining the the oven is 20 degrees hotter than it should be.
have checked with a digital thermometer and it reaches 240 degrees when the oven dial only reads max 220
any ideas please
As A1 says all stats overshoot required temp, to check temp you have to to take readings of a couple of cut outs and cut ins and work out average temp and you will find you are there or there about+or – 5 to 10′ C which is acceptable.
