ELECTRIC FRYERS - SERVICE PROCEDURES AND ADJUSTMENTS

MELT TEMPERATURE

CALIBRATION (SOLID

STATE CONTROL)

WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AT THE MAIN CIRCUIT BOX. THERE MAY BE TWO SEPARATE CIRCUITS. BE SURE BOTH ARE DISCONNECTED. PLACE A TAG ON THE CIRCUIT BOX INDICATING THE CIRCUIT IS BEING SERVICED.

1.Place a thermometer in the center of the vat at one inch below the shortening surface.

2.Allow the shortening to cool below 135￿F.

3.Remove the screws securing the control panel and allow it to swing downward.

4.Disconnect the electric harness and remove the control panel.

5.Remove the melt temperature adjustment screw sealant by gently chipping away with a screwdriver. (screw located to the right of pin #12)

6.Turn the adjustment screw clockwise to the stop position.

7.Connect a DC voltmeter between pins 13 and 15 on the electronic control board.

8.Reconnect the control panel wiring harness.

9.Reconnect the power supply.

10.While holding the control panel in your hand, turn the power switch on.

11.Set the temperature control to the frying temperature and the melt switch to melt.

12.The voltmeter should read 5 VDC.

13.When the shortening temperature reaches 135￿F, turn the adjustment screw counterclockwise until the voltmeter reads 0 VDC.

14.Place a small drop of enamel paint or fingernail polish in the center of the screw.

15.Disconnect the power and remove the voltmeter.

16.Install the control panel.

CONTROL BOARD TEST (SOLID STATE CONTROL)

1.Check the temperature of the shortening. The temperature should be below 300￿F and above 135￿F.

2.Access the control board.

3.With the potentiometer set at 0￿, turn the power switch on and check the incoming voltage.

A.120 volts, between pins 1 - 2 and I - 5.

B.208 or 240 Volts, between pins 1 - 3 and 1 - 5

C.240 Volts, between pins 1 - 4 and 1 - 5 (Export only)

4.Check the potentiometer as outlined under

“TEMPERATURE CONTROL TEST”.

5.Check the thermistor temperature probe as outlined under “THERMISTOR PROBE RESISTANCE CHART”.

6.Set the control to call for heat, the heat light should light.

7.Check for output voltage between pins 1 - 7.

8.Replace the control board if there isn't any output.
