Re: Imperial IFS50

Hi, Probably the thermocouple. It will be right at the pilot light and hooks to the gas valve. The pilot heats it up to tell the gas valve that the pilot is working. If this is an electronic ignition, It will be the flame sensor still close to the pilot and will need cleaned or replaced. Hope this helps.

I have an imperial fryer. Pilot is on but main burners don't ignite. Pilot looks normal & thermostat clicks when turned

Number 5 is your thermopile/pilot generator. It is a pilot generator that does 2 things. It holds open the valve with a safety magnet and it operates the safety valve solenoid whenever the control stat calls for heat. Overtime they get weak and will hold the pilot but not operate the valve solenoid. I would replace that pilot generator.thermopile and party on!

Hi i have a new imperial fryer and im tring to light it and cant seem to get it to work. any idea on how to get it working?

Have a lighter handy (I use one of the elongated ones for caravaners)
in-between the burners is a pilot light (top right) keep the lighter flame where the gas comes out.
On the right hand side of the fryer at the bottom is a gas valve with a little black knob.
Press and hold the black knob in and gas will come out of the pilot light and ignite by the lighter flame. You need to hold the button in for quite a while. (until it stays lit)
When it stays lit depress the little black knob and turn it anti clockwise. Gas comes out of the burners and ignites from the pilot light. When it reaches temp. it will cut out.
To turn it off turn the little black knob clockwise. To turn the pilot light off, push and turn clockwise.

When i turn the thermostate on , it turns off the pilot. what can i do to prevent this from happening?

Check the millivolt output of the pilot generator. Sounds like low millivolts. Replace the pilot generator and you should be good.

Comercial deep fryer pilot light goes out

This problem could be caused by a few different things. You should check the condition of your pilot and the thermocouple, if the pilot is weak due to being dirty you will not generate the optimum Millivolts to run the fryer, you may need to dissassemble and clean the pilot. The thermocouple needs to be correctly placed in the pilot assembly, if it has dropped down to where it is not in the flame it will not work correctly. You may need a new thermopile as it may not be generating millivolts as needed. Gas pressure can cause this as well, if the pilot goes out then the main burners come on you should check the gas pressure. One more thing to check is the hi-limit thermostat, if this is cutting out early your pilot will go out. Imperial uses a self-resetting limit, after a few minutes your fryer will relight and work until if cuts out again. If your fryer pilot stay on with the thermostat off for long periods of time and does not go out immediately when the burners come on and the pilot is clean, you may need a hi limit. This is a lot of info, I hope it helps.

Imperial fryer IFS-40

I had a very simular problem. My fryer would do exactly as you described, but sometimes the pilot light would stay on until the burners tried to re-ignite and then it would go out.
I finally had to call the gas company. They took the pilot light apart and cleaned it. The fryer works perfect now.
Hope this helps!

If your pilot lights up but the main burner doesn't light up then you have a bad pilot sensor or gas valve
