Valentine Pension 1-83. The fryer heats the oil and then the switch on electric board trips? Please help

Is the switch any good? Is power reaching the heating element? Is the element open?

Sounds like you may have a 3 phase fryer, or it is wired wrong. If you only have single phase power, it might be able to be rewired so that all three heaters are on the two main leads, this is often done at the power relay with a strap. Note the current will be much higher this way.

Defective thermostat.

Hi there!
Reset button of hi-limit switch will only pop-out when its sensing bulb sensed temperature higher tha 450F (trip temperature of hi-limit). Theramostat may be bad allowing oil to reach temp above 450F causing hi-limit to trip-off or hi-limit itself is bad tripping-off at temperature lower than 450F.
Check also the position of the sensing bulb of the hi-limit, it may be positioned touching the heat tube (for gas fryer) or heating element (for electric fryer) that's why it prematurely trips-off.

Hi there.
You can download Wells F67 electric fryer at http://www.wells-bloomfield.com, it contains conversion of wiring from single phase to three phase, just click the owner's manual on Service and Support page.

If you feed single phase into the line terminals, you will get only 1/3 the heat wattage. To get all heating elements working on single ph, you'll have to separate the common ends of the elements, then connect all 3 in parallel. Keep in mind, doing so will raise your line amperage x3 also. That may put you over the contactor's max rating. Another thing, the contactor will activate on only one sequence of single phase. You may need to move the line to another 2 of the 3 connections.

When the whole unit shuts down including the pilot light the thermocouple is not working properly. The thermocouple is what tells the gas safety valve that the pilot light is lighted. When the thermocouple fails and does not send the milli-volt (mv) signal to the gas safety valve due a failure the gas safety valve turns off the gas supply. (i.e total shut down)
If you have a handyman around you can have him disconnect the thermocouple from the gas valve control and clean the mating area in the gas valve and on the bitter end of the thermocouple. After cleaning then reconnect the thermocouple. This sometimes corrects the problem. FYI you can get a thermocouple at most any large appliance parts supply. (You will need to the know total length) It would be even better to have the old one in hand during the trip to the parts store.

Thanks for using FixYa,

It probably is a problem with the thermostat. The reset button is probably a high limit. The high limit is a safety device to turn the fryer off if the oil gets too hot. Normally they will "trip" somewhere between 375 - 450 degrees F for commercial fryers. I would suggest placing a temperature probe in the oil and see what the oil temp is when it trips. If it trips at a temp below 375, it is a bad high limit. If the thermostat is set at 350 and the temp goes over 400 then the thermostat is bad.

I have 3phase blue seal electric fryer how can it be converted to single phase please? i have been toild it can and it will take 45amp fuse. please advice.
