(5) Allow the clock motor to drive the cam for two minutes or so and allow the lever to drop into the slot. The
control (SPDT switch) should de-energize the outdoor fan motor and the reversing valve solenoid The
outdoor fan motor should stop and a "swooch" sound will indicate the switching of the reversing valve to
the cooling mode. The outdoor coil should begin to get hot. If not, replace defective defrost control.
(6) Remove the sensing bulb from the brine solution and bring temperature up to a min of 56 degrees Fahren-
heit (12 degrees Centigrade). When the sensing bulb temperature reaches 56 degrees Fahrenheit (12 de-
grees Centigrade) the control (SPDT switch) should energize the outdoor motor and solenoid coil, putting
the system back in the normal heating mode. If not, replace defective defrost control.
(1) Tag and disconnect all wires to the defrost control. See Figure 4-32.
(2) Remove the two screws (1) from the defrost control (2) and pull the defrost control out of the control box (3).
Feed the sensing bulb (4) up out of bracket on left side of outdoor coil, through the compressor base pan.
(1) Install the defrost control (2, Figure 4-32) in the control box (3) with two screws (1).
(2) Connect the wires as tagged and remove tags.
(3) Feed the sensing bulb (4) down through the compressor base pan and slip it into the clip on the left side
of the outdoor coil.
(5) Install both front door assemblies. See para 4-17.
(6) Install left side door assembly. See para 4-19.
