Possible Solutions
1. Green LED light (indicates demand for refrigeration) must be on.
Box temperature must be higher than set point temperature. Check display
Temp Setting for “SP”.
2. Liquid line solenoid must be energized. Check solenoid coil with small
screwdriver to confirm there is magnetic force. If no force, check voltage at
terminal 4 and N OUT, check solenoid coil wire splices in conduit box.
3. Check, with gauges, condensing unit low-pressure control setting. Is it
adjusted low enough to cut-in?
4. Contact Factory
1. Yellow LED light (indicates defrost cycle mode) must be on.
Defrost cycle will not start if “evap” sensor is above 55ºF. Ensure refrigeration
mode has run long enough to reduce “evap” sensor temperature below 55 ºF
2.Check for Voltage between terminal 3 and 1 IN. Check all heater wire
spade connections, splice connections and jumper connections.
