Question about Pitco Frialator 45C Deep Fryer

2 Answers

I have the Frialator 45 C +. Non electric set up for propane. My problem started with the pilot light being blown out once temp was reached as well as a fire originating at one of the orifice spuds (second from left just in front of gas valve). The next day I could light the pilot but it would not stay lit on it's own. I pulled the burners out to clean, they were very dirty, I also replaced the thermopile and made sure the pilot flame was burning right on it. The pilot will still not stay lit. I know that when the fire burst out around the orifice it became hot enough to melt the top of the plastic pilot knob as well as the rubber handle on the drain valve. So my questions are: Could the heat have deteriorated a component in the gas valve? Could the problem be in the pilot tubing or somewhere else in the gas line? I imagine the problem not to be the thermostat but what about the hi limit wire and high limit switch? I'm not so sure what these do. I did try to reset the hi limit switch as the manual suggested though it does not give clear instructions what that entails. Is it just pushing the switch with your finger or is there more to it than that? Here is a link to Pitco's sight where the spec, manual and parts can be viewed. http://www.pitco.com/economy.htm I'm up in Alaska and any part has to be special ordered, so guess work can be pretty expensive. Thanks for any advice and help. George

    I don't feel like I've gotten any direction from this response. Before I go spending hundreds of dollars on parts I need some guidance as to what the most logical step should come next or what kind of testing I can do to determine what part is actually failing. What about the hi limit switch/wire?

Hi, I've reviewed your problem, and understand that the pilot is failing to stay lit. YOu said there was a small fire that did get hot.

The gas valve uses a very low current solenoid to maintain a pilot. the thermopile generates the current to hold the pilot valve open. It is possible that you ruined the gas valve. If you have a multimeter, you can check this solenoid by testing the leads where the thermopile connects to the gas valve.

The center of the thermopile is one lead, and the casing is the other. Use a good digital VOM to test this. If you find a reading of infinity, or a zero ohms, then most likely the gas valve is ruined.

There should not be any other component in the pilot circuit. The other sensors control the actual flame.

Could the heat have deteriorated a component in the gas valve?
offcourse that is quite possible and under the range of acceptance


Could the problem be in the pilot tubing or somewhere else in the gas line?
pilot tubing is real sensitive and this the one that has to be taken care of

what about the hi limit wire and high limit switch?
when trouble hits hard science cannot guarantee or define limits

My pilot stays on on my propane furnace but will not light up


The Little Giant units use a Unitrol gas valve very similar to a water heater in the home. #1,urn the Unitrol gas valve to the "PILOT" position to ignite the pilot. Depress the plunger and hold it down then push the spark igniter button until you can see the pilot flame ignite.
You have a lit pilot so this is not a problem for you.
The pilot light stays on continuously by design.
Once the pilot flame is established, you then turn the on/off/pilot valve to the "ON" position and set the thermostat to the desired temperature range., it should then fire its main burner until the desired temperature is reached. Once the temperature is reached, the main burner will shut off and the heater will go into a standby mode with the pilot flame still burning.
If you have turned the pilot valve to on and set the temperature high, it should come on, if not a new gas valve is required, they can be very difficult to replace due to rust.and most cases require a new unit,

Pilot and burner light then gas shut off model 7900


How many degrees before it reaches desired temp, does it shut off? A thermostat is designed to shut the furnace off a couple/ few degrees before it reaches set temp. It has what is called a heat anticipater, which shuts the burner down, and lets the blower use the remaining heat from the heat exchanger to bring it up to desired temp making it more efficient. If it is more than a few degrees, replace the thermostat. You can jump out the red and white wires to confirm the faulty thermostat. If by doing this, the furnace never shuts down, until you separate the red and white wires. That confirms a faulty thermostat. Hope this helps someone.

When the pilot light button is released the flame goes out. (pitco propane fryer) - unsure of model number as data plate is worn. Does the thermopile need replacing ?


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.

Flame goes off when temp. reaches 250 degrees, use to stay on 350 degrees without problems an them started acting up and won't reach that temp any more, disconnect the pilot automaticly


Hi limit device trips prematurely (should only trip when oil temp reaches 450F). Check if the hi limit sensing bulb (located inside the fryer tank, between fire tubes) is not touching the fire tube because if it does, it will sense the heat from burner flame which is much higher than oil temp.

Typically there is a safety device directly above the pilot light that must be up to temp for the gas to flow. You did not specify if the pilot is lit. If not, hold the lighter at the pilot light while depressing the button for one minute. This allows the sensor to warm to operating temp, thus allowing gas flow. Once pilot is lit adjust the temperature accordingly.

A pitco frialator in a restaurant will operate for about 5-6 hours and then blow the pilot light and burner out. I have put a thermometer in the oil, watched it work and the oil temps wont exceed 375...


I assume that the thermometer you are using is calibrated. You have to check the continuity on the hi limit terminals once the pilot light shuts off. If it has no reading, the hi limit trips prematurely and it needs replacement.

Pilot shutting off once temp reached


Hello. It is hard to say exactly what is going on, but here it goes. First, are you sure it is getting to temp? use a thermometer. if so, then, you could have a weak hi limit, tripping at 350 or 375, instead of 450. Do you have to reset it? or let it cool down? or does it light right back up. If not, then you probably have a weak thermopile, not producing the correct millivoltage ( less than half of a AAA battery ), it normally is 450 to 750 millivolts.You can test this with a multimeter, one side to the thick copper wire coming from the pilot, and the other at one of the hi-limit wires, DC voltage please. Grease could be on/in any of the aforementioned components, causing a poor connection, with less than half an AAA battery, it does not take much to cause a problem. A dirty pilot, or low gas pressure could also cause a problem.

Hope that helped, and thank you.

Lighting the fryer


If this is a milivolt unit, meaning no solid-state or computer/digital controlled. You would need to turn your gas valve to the pilot position, then press in and hold until you can light the pilot using a lighter (this may take several minutes, to bleed the air from gas supply) once there is a pilot flame present, you will need to hold the valve button in for about 45 seconds to heat the thermalpile. Once pilot is lit, thene turn to on position and proceeed to turning thermostate to set temp.

Fryer shuts down including the pilot light once it reaches temp


Hi there, try here and check your state, and pick a company close to you, they will either have the part you need, or can get it relatively quickly.
