Frymaster Fryer Codes & What They Mean

Picture

Many deep fryers from Frymaster utilize a digital readout systems, allowing users to program timed frying and holding cycles as well as error readouts. Whether you’re looking to access a boil out code, set temperatures or diagnose an issue, we have Frymaster error codes for 3000 Controllers and CM III.5 computers.

Code E26

  • Error message – RECOVERY FAULT CALL SERVICE

  • Error message 2 – HIGH TEMP ALARM
  • What does it mean? – The code displays if the oil temperature has risen by 40 degrees Fahrenheit (4.4 degrees Celsius).

Frymaster CM III.5 Error Codes, Boil Out & Recovery Time

The CM III.5 can be affected by electrical storms or fluctuations in electric current. If your computer isn’t functioning properly, try to reset it by unplugging it and plugging it back in.

Fryer Codes

  • PROB – The Frymaster PROB code means the fryer has a failed temperature probe or a failed controller. Either way, you will have to call Frymaster.
  • HOT – If you see this error, turn the fryer off immediately and call Frymaster. This warning indicates a frypot temperature above 410F. It is very likely the oil in the vat has been ruined from this high temperature.
  • HELP – The Frymaster HELP code will display if there’s a heating problem with your fryer. Be sure to turn the fryer off and contact Frymaster.
  • CALL TECH – This means the memory chip or its support circuit has failed, and, you guessed it, you need to call Frymaster.

Boil Out

If you’re just looking for a code to initiate the boil out feature, read on. But first, make sure you know the procedure. Frymaster has created a series of helpful videos to walk you through the boil out process, whether you have a unit that will automatically begin or an older unit that has a specific temperature setting for boil out. Of course, it is also advisable that you have a copy of your Frymaster manual to make sure you have the correct procedure before you begin.

Recovery Time

The recovery time is the amount of time your fryer takes to increase the temperature from 275 to 325 degrees Fahrenheit after product is added (which lowers the temperature in the fryer). This number is automatically monitored by the Frymaster CM III.5 computers to help you determine whether your fryer is heating efficiently. To view the recovery time of your fryer, press the Program Mode button (the one with the checkmark) and “CODE” should appear. Enter the code 1652, and the recovery time will appear for 5 seconds.
