Hi there.

Ensure that the unit receives the gas pressure required on the nameplate. Check the thermopile, it should be free of soot or any dirt, and try to tighten all wiring connections.Regards.

7 flashes on ignition module's diagnostic led indicates that the flame rod is shorted to ground. Check the igniter tip's clearance to the pilot assembly and adjust if necessary. Also check the igniter cable for damaged insulation.

Check if the flame quality of the pilot is good. Small amount of voltage generated by thermopile used in energizing pilot main valve coil during fryer operation relies on the quality of pilot flame, also, the thermopile itself should be free of soot or any form of dirt in order for it to absorb the heat from pilot flame.
Check also the gas pressure, it should meet the gas pressure required on the nameplate.

I think that the gas valve is defective and needs replacement. Visit http://www.middleby.com and go to PITCO web, you will be able to locate there the nearest authorized parts and service dealer in case you need parts and service.

Check the thermopile, it must be free of dirt or soot so that it can absorb enough heat from pilot flame and in turn can generate the right amount of voltage to energize pilot and burner coils.
Check also the gas pressure, it should be of standard as required on the unit's nameplate.

Check the hi limit sensing bulb, it should not touch the fire tube, when it does, it will sense high temperature which will trip its mechanical contacts and will shut pilot and burner flames.
Make also sure that the thermopile is free of soot or any form of dirt and is properly heated by the pilot flame.

If the wires on hi limit were cut and shorted, it is possible that the hi limit is bad and needs to be replaced as soon as possible because it is the safety device of the fryer.
Hi limit is designed to cut burner flame in case oil temp reached 450F to avoid further damage on life and property.
Washers need to be tightened/ replaced to correct burner alignment. It is not safe to operate a fryer with misaligned burners.

If you are asking about thermostat calibration, visit whttp://ww.middleby.com and go to Pitco web, you can download operations and owner's manual that includes thermostat calibration.

Make sure that the filter system is correctly assembled so that oil impurities wont enter pipes and clog the system.

The thermopile on gas operated equipment acts as small voltage generator when heated that energizes the pilot valve and main valve of the gas valve,. Without it, you will not be able to fire up your fryer.

You can check the voltage generated by thermopile using a voltmeter. Set the voltmeter on milli-volt setting then heat up the thermopile. When properly heated, it can generate 500 to 750 milli-volts.

Try removing the oil and boil out the fry tank.

CFG error on controller board can be cleared by resetting the controller back to factory setting and by doing this, all program added after the factory setting will be erased so you have to reprogram them again.

Try to clean the thermopile, it should be free of dirt/ soot so heat from pilot flame could be sensed better. Thermopiles generate small amount of voltage when heated properly, the voltage it creates is used in energizing gas valve solenoid coils.
Check also if the hi limit is good, small amount of voltage thermopile generates pass through hi limit terminals.

There may be soot/ carbon build up inside the fire tubes that's why flame crawl all the way to flue. Also check if your fryer receives the right gas pressure and type as rated on the nameplate.

Visit pitco web at www.middleby.com, there are manuals which will help you in cleaning fryers.

There are different thermocouples for different type of gas valve. You can order the thermocouple for your pitco fryer at www.middleby.com and look for the local service/ sales office in your at pitco website there.

Try first to clean the thermopile. If it has accumulated soot/ carbon, it will not sense enough heat from the pilot flame to generate small amount of electricity to energize the pilot valve and main valve of gas valve.

You can find the model number at the nameplate located at the back of bottom compartment door.
