Replacing the Heating Contactors (Electric)

Each well of an electric fryer requires two switching contactors. The first in line is the primary contactor and the second in line is the heat contactor. When open, the primary contactor does not allow power to flow to the heat contactor. When closed, the primary supplies voltage to the heat contactor. When the heat contactor is open, no voltage is supplied to the heating elements. When the heat contactor closes, voltage is supplied to the heating elements.

To avoid electrical shock or property damage, move the power switch to OFF and disconnect power.

Remove electrical power supplied to the unit.
Remove the control panel.
Perform a check on the contactor as follows. Wires should be removed and labeled to obtain an accurate check of contactors.

Test Points	Results
From 23 to 29	Open Circuit
From 24 to 28	Open Circuit
From 25 to 27	Open Circuit
From 30 to 34	Open Circuit
From 31 to 35	Open Circuit
From 32 to 36	Open Circuit
From 33 to 37	Ohm reading 1700
From 22 to 26	Ohm reading 415

Re-apply power to unit and turn power switch to ON.

SHOCK HAZARD

To avoid electrical shock, perform relay checks or transformer checks as described as instructions.

The following checks are performed with the wall circuit breaker closed and the main power switch in the ON position. Extreme caution should be taken. Make connections before applying power, take reading, and remove power before removing meter leads, or electrical shock could result.

Check voltage and if either contactor is defective it must be replaced.

Test Points	Results
Heat Contactor	The voltage should read the same at each terminal.
From terminal 34 to 35
From terminal 35 to 36
From terminal 34 to 36

Test Points	Results
Primary Contactor	It should correspond to the voltage stated on the data plate.
From terminal 27 to 28
From terminal 28 to 29
From terminal 27 to 29

Replacing the Heat Contactor

To avoid electrical shock or property damage, move the power switch to OFF and disconnect power.

Remove only the wires directly connected to the contactor being replaced.
Label wires for replacement.
Remove the screws securing the contactor to the shroud, and remove contactor.
Install new contactor.

Replacing the Primary Contactor

To avoid electrical shock or property damage, move the power switch to OFF and disconnect power.

Remove only the wires directly connected to the contactor being replaced.
Label the wires fro replacement.
Remove the screws securing the contactor to unit and remove contactor.
Install new contactor.
Reinstall the control panel.
Reconnect power to the fryer and test for proper operation.
