Troubleshooting Guide
WARNING: These guidelines are intended only for qualified service personnel familiar with
troubleshooting procedures and high voltage.
Problem
SmartVap TM control display
does not power up and
display zone temperature
Evaporator fans do not start
(Display OK and powers up)
Possible Solutions
1. Check for voltage (200 to 240V) at 1 IN and N IN (see wiring schematic
for terminal locations)— If NONE, check for voltage at field connections L1
and L2 or back at main panel service entrance. (Note: 3 and 4 Fan models have
inline 20 or 25A fuses (type LPCC or CCMR). Reject type fuse MUST be used
and inserted with smaller diameter end into holder, large diameter in
cap. If fuse(s) are blown, check/repair wiring for short before replacing fuse(s).—
If all above VOLTAGE OK, check voltage at 1 OUT and N OUT. If NONE then
check both 15A ceramic fuses. If fuse(s) are blown check for wiring short before
replacing fuse(s). (250V Rated Type ABC or MDA 15A must be used).
2. If above voltage OK, then check phone cord and cable connection at
module end. (Ensure cable is snapped in) CAUTION: KEEP FINGERS AWAY
FROM POTENTIAL VOLTAGE (terminal 3) when checking.
3. Push and hold “Up” and “Down” Display buttons together for 5 — 10
seconds. This will re-boot & reprogram the electronic clock to factory settings.
Ensure “Ed” mode (Electric Defrost) is selected.
4. Contact Factory
1. Check to see if display indicates “Defrost” mode (Yellow LED on).
Evaporator fans are designed to be shut off during defrost and after a defrost
cycle fans will not re-start until temperature reaches 25ºF at “evap” sensor.
2. Check connection of orange jumper from C to 1 OUT. Check voltage at
C and N OUT
— If NONE, see fuse checks above on “Display” troubleshooting
— If OK, check voltage at F and N OUT, If OK check fan wiring and voltage
at plug (motor end).
3.Check fan delay temperature setting (Factory pre-set at 25ºF) and re-
adjust higher if required.
4. If fan delay setting is OK, check sensor at rear of unit cooler in return
air stream (top left hand side -in front of fins) Is it tagged “ZONE”? If tagged
“Evap”, switch sensor locations. (Move “Evap” sensor to correct location at return
bends.)
