Troubleshooting Guide : Chassis Low Voltage Controls

 

Troubleshooting Low Voltage Chassis Controls

 

Troubleshoot chassis low voltage using the low voltage chassis harness without the need to pull out chassis or re-
move chassis top cover.  Check resistance readings using a multi

-

meter probe to confirm continuity across: safeties 

(HPS, LPS), sensors (EWT, LWT, RST) and valves (ASOV, REV).

 

HPS 

-

 High Pressure Switch: 

 

• 

Check continuity between that switch is Normally Closed.

 

LPS 

-

 Low Pressure Switch

 

• 

Check continuity between that switch is Normally Closed.

 

RST 

-

 Refrigerant Suction Temperature Sensor

 

• 

Check resistance for 10KOhm sensor across RST  and Common (white).

 

EWT 

-

 Entering Water Temperature Sensor

 

• 

Check resistance for 10KOhm sensor across EWT  & Common (white).

 

LWT
