Frymaster M3000 manual Typical sensor-related failures

Page 12

LOVGeneration II Technical Reference

If oil is surrounding the heater, the oil will prevent the heater from ever reaching its setpoint. Once oil is removed during filtration, the heater reaches setpoint and cycles a thermostat every four seconds. Since the cycle is only four seconds long, the seven second delay is not made and the gas valve won’t open.

The 120VAC is on T2 in the control box traveling in on pin 11 of J3 and out pin 7 on J1 (DV) or pin 7 on J3 (FV).

Typical sensor-related failures:

Low temp but no call for heat (heat light),

Stuck in melt cycle with no call for heat,

Filter error (IS VAT FULL?) with oil in the filter pan (no oil in the vat).

If the computer doesn’t exit melt cycle or continues to display low temp and does not heat, ensure that the gas supply, gas valve, and other components are working properly. If no heat lamp illuminates because no call for heat is initiated, check the following (see diagram below):

Power to oil sensor (from previous basket lift relay on interface board K1(DV) or K4 (FV)). Check pin 7 on J1 (DV) or pin 7 on J3 (FV) for 120VAC.

Power to heater/relay coil on relay board. Check voltage to the coil on pins 8 and 1 to ensure that 120VAC is present with oil in the vat. If the vat is empty, the power will cycle 4 seconds on, 4 seconds off.

Check between pin 3 and 2; 5VDC for air and 0VDC for oil. A common message for a shorted harness or issue is IS DRAIN CLEAR? with oil in the filter pan.

Check ground on pin 2 on relay board to stud for a secure ground.

Check AIF communication harness. Interrupted communication will prevent the fryer from heating.

If the oil level sensor is cycling 4 sec. on/off and oil is surrounding the sensor, the sensor may have a carbon build up that is self insulating the sensor. Use a no scratch pad to remove carbon build up.
