1.
Check the power to the heaters (230vac)
a.
Disconnect and test the voltage (230vac) at con 10 for the top heater and
at con 12 for the bottom heater. If the correct voltage is not present
replace the main PCB.
b.
If the correct voltage is present then go to step 2.
2.
Check for proper destination of the wires to the heaters.
a.
With the power off, check the wires to verify that the wires from CON10
go to the top heater, and that the wires from CON12 go to the bottom
heater. If incorrect, wire them correctly.
b.
If correct, go to step 3.
3.
Check the resistance of the heaters
a.
With the power off check the resistance of the heaters by removing the
connector from the board and testing across the terminals in the plug for
the proper resistance (29 ohms for the T-110 and 26 for the T-165). If an
incorrect resistance reading is found, first check all the connection and if
they are determined to be good then replace the heating element.
b.
If the resistance is found to be good replace the board.
