Model 104 Electrical Troubleshooting
Following are the paths of power necessary for
component operation.
Auto Mode of Operation
L1 power must travel through thehigh pressurecutout
switch,thecontrolswitch(terminals1and2),tothecoil
of the beater relay (terminals 5 and 6) to the timer.
When the beater relay closes, L1 power goes across
theswitchpoints3and4, tothe door switch. (Thedoor
must be installed to operate the beater motor.)
If the door switch is closed, L1 power goes across the
switch points “C” and “NO” to run the beater motor . If
the timer is set, it will supply L1 power to the
compressor relay.
Eject Mo d e of Operation
L1 power must first pass through the HPCO switch to
the control switch (terminals 5 and 6) and then to the
coil of the beater relay.
The switch points 3 and 4 close and L1 power is
supplied to the beater motor. The timer is not active,
so the compressor does not run.
