Dean fryer pilot lit but burners won't come on
The bimetallic sensor that shuts the gas off if the pilot light blows out is malfunctioning,you need to have it serviced.
There is a thin piece of metal that sends an electrical signal to the main burner valve when it heats up enough,if the flame is extinguished the gas shuts off so the room doesn't fill with gas and explode

I have a four frypot dean deep fryer after moving and cleaning from around equiptment on of the four pots wont fire up is it the thermo pile or should look somewere else?
Hello! You did not include the model number in your question. With the model number I can look it up and tell a great deal about the appliance without actually physically seeing it.
You will need a multimeter to determine if the thermopile is good but before running any voltage test you should make sure the thermopile isn't charred and dirty on its surface. If so you can clean it up with sandpaper first, then check to see if the pilot stays lit. Also the pilot flame should be appropriate in size and should be a clean blue flame and the flame should be making good contact with the thermopile. The pilot will need to be cleaned if the flame is not right. Some gas appliances have both a thermopile and a thermo coupler..
At the main gas valve there will be some terminal screws with wires connected. You will be probing the two screw terminals "TH TP" and "TP". The multimeter should be set for DC voltage. Now before testing you will need to light the pilot and keep it on for a few minutes. Then with the gas turned back off check for millivolt readings at the two terminals. in the absence of the flame you should be reading 325 millivolts or more. If your reading is much less than that then your thermopile is defective. With the flame going the voltage should read near 125 millivolts or more. If the pilot won't stay lit and there is not a thermo couple but the thermopile passes the meter test then the problem is going to be in the gas valve. On occasion I have resurected the gas valve by giving it a sharp blow with a wrench. Sometimes the valve can develop debri in the form of a small granule of dust or corrosion and a swift blow is all that was needed to clear the valve and regain operability. But if that doesn't work don't beat the valve up! You can buy a rebuild kit or just buy a new valve.
