REPLACEMENT OF MAIN COMPONENTS
I . Assemble the pins in original positions.
J. Connect the connectors of the evaporator defrost heater to them of the thermal fuse
* NOTE
Why is always 115 voltage detected between connectors of the evaporator defrost heater
in the main harness?
The SNUBBER(located Main PCB) holds two AC power lines simultaneously.
The SNUBBER prevents Main PCB malfunction from sparks occurred by other electrical
component’s ON/OFF. (SNUBBER = Spark killer)
Because of the SNUBBER, 115 voltage is always detected, but electrical current in this case is
very little(small Amps.). So, this electrical current is not enough to operate the evaporator
defrost heater.
How to measure the Amps. of the evaporator defrost heater.
Disconnect the connectors of the evaporator defrost heater.
Then, prepare the additional Power Source(115V/60Hz) and the Amp. Meter.
Connect the evaporator defrost heater to the additional power source and read amp. value from
the Amp. Meter.
