Oven probs i have an older blodgett 2 deck oven... i get it lit up heats up to temp and completely shuts down i have replaced the thermocoupler now twice still didnt change anything.

Door switch, gas valve, temperature control, selector switch?

Check to see if hood is blowing air down oven flue.

Hello Peter;

My name is Peter. I am a retired field service appliance technician.

I recently repaired a oven that would be off as much as 200 degrees. The normal operation of your oven is to rise 20-40 degrees above set temperature and shut down until it drops 20-40 degrees below set temperature, turns back on and repeats the cycle again.

Generally, there are only three components that control your oven temperature:

1.) The Heating Element - If you are getting heat your heating element may be good. To be on the safe side inspect the two connections on the back wall to ensure they are not corroded.

2.) The Thermocouple - There are several different thermocouples depending on your model and if your have gas or electric. These are easily replaced.

3.) Oven Control - Here again there are several different controls, both mechanical or digital.

I just purchased a oven thermocouple and a reconditioned digital control over the internet for under $75.00.

IF YOU HAVE A DITIGAL CONTROL - GROUND YOURSELF BY TOUCHING BARE METAL. STATIC ELECTRICITY WILL KNOCK OUT A BOARD.

So, go into the following website put in your model number and select parts. Several diagrams with part numbers will appear. Your model number is on a metal plate on the face of your oven after you open the door.
Fine your thermocouple and oven control. Copy these part numbers and search the internet for best price.
First, replace the thermocouple. If this solves your problem then return the control for credit if not install the oven control. The highest probably is you have a bad thermocouple

to confirm check the Ohm draw on the temperature probe, i am not sure what is the correct one but you can check online at blodgett if probe okie then you will have an issue with the temp controller there possible the potentionmeter is worn out.....good luck

if its a pilot lightr that stays lit all the time,then its the thermocouple next to the pilot light thats bad and cant keep the pilot on

I have one that won't light at all, what could the problem be?

300 far. or cels if its celcius its to high they should run at about 260 or the high temp sensor will shut it down how fast is your belt running it should be 6.30 to 7.00

had the same problem, safety gas valve is sticking get a small hammer and tap saftey valve. Just bought a new saftey valve about 3 weeks ago pilot light lite but now flame. I have a blodgett oven made in the 60s. Blodgett is getting away from there swithes that they have been replacing them with a replaceable thermocouple.made by robert shaw. My supplier said that they are not on the market yet. oops! good luck from oswego ny pizza villa.

either the flame sense isnt sensing the flame or the heat board is bad.go to the second burner and you will see a probe,clean it up with sandpaper and see what happens let me know
