Form 2 Common Malfunctions
Malfunction
Description
Reason Solution
The machine does not
work.
1. Power failure
2. Power cord is loose.
3. Control power fuse is broken.
1. Turn off the power switch and
check the power.
2. Find out the problem and fix it.
3. Replace the fuse.
The machine has low
Heating capacity
1. Refrigerant is insufficient.
2. Water pipe’s thermal insulation
performance is poor.
3. Dry filter is clogging.
4. The heat exchanger with air has
poor cooling.
1. Check if there is leakage and
note the standard quantity of
refrigerant.
2. Strengthen water system
insulation function.
3. Replace the dry filter.
4. Clean heat exchanger with air.
The compressor does
not work
1. Power supply or the controller is
broken.
2. The compressor’s contactor fails.
3. The wire is loose
4. The compressor’s overheating
protection works.
1. Find out the reason and solve it
accordingly.
2. Replace the contractor.
3. Find out the loose point and fix it.
4. Identify the reason of
overheating and then turn on the
machine after trouble shooting.
The compressor works
noisily
1. Internal components are
damaged.
2. Frozen oil is not enough.
1. Replace the compressor.
2. Add enough frozen oil.
The fan does not work
1. The capacitor is broken.
2. The screw is loose.
3. The motor is broken.
1. Replace the capacitor.
2. Tighten the screw.
3. Replace the motor.
The machine does not
produce heat, while the
compressor is working.
1. Refrigerant spreads out totally.
2. The compressor is broken.
1. Check if there is leakage and
fulfill the standard quantity of
refrigerant.
2. Replace the compressor.
Exhaust flue pressure is
too high.
1. Refrigerant is too much.
2.Fluorine-way system contains
non-condensable gas.
1. Expel excessive refrigerant.
2. Exclude non-condensable gas.
Suction pressure is too
low.
1. Dry filter is blocked.
2. Refrigerant is too little.
1. Replace the dry filter.
2. Check if there is leakage and fix it.
