3.4 Trouble-shooting chart
TROUBLE PROBABLE CAUSE REMEDY
Freezing or blockage in
the pipe with propylene
glycol
1. Percentage of water above
normal.
1. Remove and replace all of the solution
according to the percentages
*according to your supplier.
Compressor starts but
remainsin start windings.
(Single phase only)
1. Low line voltage
2. Improperly wired
3. Runing capacitor shorted
4. Starting capacitor weak
5. High discharge pressure
1. Ask power company to increase volta-
ge to no less than 10% below nameplate
rating or install transformer.
2. Check wiring against drawing. Check
wire size.
3. Check by disconnecting runing capa-
citor.
4. Check capacitor, replace.
5. Check water regulating valve; check
water or air condenser and clean, if ne-
cessary. Check discharge shut-o󰀨 valve
Starter burned out. 1. Low line voltage.
2. Excessive line voltage.
1. Ask power company to increase volta-
ge to not less than 10% below nameplate
rating or install transformer.
2. Ask power company to reduce volta-
ge to maximum of 10% over nameplate
rating.
Starting capacitors burn
out. (Single phase only)
1. Voltage too low.
2. Impoper capacitor.
1. Ask power company to increase volta-
ge to not less than 10% below nameplate
rating or install transformer.
2. Replace capacitor with properly rated
capacitor, as listed in manual.
Running capacitors burn
out. (Single phase only)
1. Excessive line voltage. 1. Ask power company to reduce line vol-
tage to not more than 10% above rating
of motor.
Unit operates long or con-
tinuously.
1. Shortage of gas.
2. Dirty condenser.
3. Moisture in system.
4. Compressor failing.
1. Repair leak and recharge.
2. Clean condenser.
3. Evacuate and recharge system.
4. Check compressor for proper pressu-
res. If inadequate, replace compressor.
