The mixture of gas and liquid refrigerant enter the
accumulator after leaving the evaporator coil. The
accumulator prevents any liquid refrigerant from
reaching the compressor. The compressor evacuates
the cool refrigerant gas from the accumulator and
compresses it to a high pressure and temperature to
repeat the process.
5.3 Troubleshooting
No dehumidification, neither blower nor
compressor run with fan switch OFF.
1. Unit unplugged or no power to outlet.
2. Humidity control set too high or defective (Sec.
3.1 & 5.9)
3. Loose connection in internal wiring.
Some dehumidification, blower runs continuously but compressor only runs sporadically with fan switch
OFF.
1. Unit is in defrost cycle (Sec. 3.3 & 5.10).
2. Defrost thermostat defective or loose (Sec. 3.3 & 5.10).
3. Loose connection in compressor circuit (see Fig. 4).
4. Defective compressor overload (Sec. 5.6A).
5. Defective compressor (Sec. 5.6).
6. Defective relay (Sec. 5.8).
7. Defective defrost timer (Sec. 5.10).
No dehumidification. Blower runs but compressor does not with fan switch OFF.
1. Bad connection in compressor circuit (Fig. 4).
2. Defective compressor capacitor (Sec. 5.6A).
3. Defective compressor overload (Sec. 5.6A).
4. Defective compressor (Sec. 5.6).
5. Defective relay (Sec. 5.8).
6. Defective defrost timer (Sec. 5.10).
7. Bad connection in pump circuit (Fig. 4).
8. Pump float switch or safety switch open (Sec. 5.11).
9. Pump motor defective (Sec. 5.11).
Blower does not run. Compressor runs briefly but cycles on & off.
1. Loose connection in blower circuit (Fig. 4).
