Rear Cruise Aire - jesupbill - 08-15-2005 02:58
For some reason my rear cruiseaire has stopped. The fan will not come
on or anything. The breaker in the box is on but it seems like there is
no power to the A/C or some cut-out switch has turned it off. Front
unit and mid-unit work fine.
Any suggestions?

Hi Bill:
Remove the 4 screws holding the control to the wall. Pull it out gently and
behind that on the back wall there should be a cover plate with the
electrical connections. This is where the power from the circuit breaker in
the main panel comes in. Then it splits, going to the fan in the evaporator
( inside unit) and the compressor in the condenser (outside unit).
The color codes on the terminal strip are:
--------------------------------------------------------------
green (ground)
black (Line 1) Power In
white (L2 or Neutral)
-------------------------------------------------------------
orange (fan speed, evaporator)
purple (compressor)
blue (no connection unless optional heat pump)
red (fan speed, evaporator)
white (L2 or Neutral)
evaporator wiring:
orange
red
white
green
compressor wiring
purple
black
white
green
This is assuming that your unit is the ACA 14U
I need the number on the switch unit and compressor unit to give you the
exact wiring and pin umbers and color codes. There are 14 to 18 different
configurations with heat pumps, time delay relays, reversing valves and
pressure equalizing valves.
Why you pulled the switch unit out is to check to be sure that the in
coming power from the main panel is actually getting to the terminal block
wiring. Even though the circuit breaker is not tripped in the main panel,
the neutral, ground or even hot wire may have vibrated lose in the main
panel and that is why "both" units are not doing anything. Pull the grey
panel covering off the main panel and with power off, check all wiring for
connection and tightness. There is a motor thermal cut off relay on the
evaporator blower motor as well as on the compressor in the condenser.
