CheckpointWhy it matters
RefrigerantMust be R134a; conversion from R12 or R600a requires full system redesign. ​
Evaporating temperatureEnsure design conditions fall inside −35 to −10 °C LBP range. ​
Condenser and capillary sizingMatch to 265–295 W capacity to avoid flood‑back or high‑head faults. ​
Voltage stabilityMains should remain within 187–254 V; more unstable grids may justify wide‑voltage models like PE90H1F‑9. ​
Start componentsRSCR start kit (PTC + capacitor) must match GMCC’s specified values to guarantee torque and reliability. ​

compressor windings CSR pin configuration common start run terminals, PTC relay overload wiring and multimeter resistance testing guide
Measurement pairIdentification ruleTypical range*
C–RRun winding (lowest resistance)About 1–5 Ω on small fractional‑HP units. ​
C–SStart winding (medium resistance)Usually 3–11 Ω, often 3–5 times C–R. ​
S–RStart + run (highest resistance)Equals C–S + C–R by ohm’s law. ​
Motor typeComponentsTypical use caseStarting torque
RSIR (Resistance Start Induction Run)Start relay + start winding, no capacitorSmall domestic refrigerators, low starting torque. ​Low
PSC (Permanent Split Capacitor)Run capacitor in series with start windingSmooth, efficient operation, good for low starting load. ​​Low–medium
CSIR (Capacitor Start Induction Run)Start capacitor + relay, start winding only during startHigher torque for larger compressors up to ≈ 3/4 HP. ​High
CSR (Capacitor Start Capacitor Run)Start capacitor + run capacitor + potential or current relayVery high starting torque for hard‑start conditions. ​Very high
StepConnectionFunction
1Line (L) feeds the overload protector, which then connects to COverload opens on excessive current or shell temperature. ​
2Solid‑state relay/PTC connects between C and S with start capacitor in series if CSIR/CSRProvides high initial current to start winding, then increases resistance and drops out. ​
3Line (L) also connects directly to R through the control circuit (thermostat, contactor)Supplies continuous voltage to run winding during operation. ​
4Run capacitor connects between S and R in PSC and CSR systemsImproves running efficiency and torque. ​​

Carrier Pro-Dialog+ Tripout shutdown alarm, access denied message and troubleshooting steps by Mbsmgroup
ItemDescriptionPractical role in diagnosis
Tripout statusFault shutdown condition in which the unit is locked out until reset. ​Confirms that a safety event has occurred and that automatic restart is blocked.
Shutdown alarmAlarm state where the controller stops the unit due to one or more active faults. ​Guides the technician to consult alarm menus and history before attempting a restart.
Safety inputsDigital contacts for HP, LP, flow switches, overloads, freeze stats and interlocks. ​Identifies which protective loop opened and where to begin physical inspection.
Alarm history menuPro-Dialog function that stores a list of previous alarms and operating states. ​Helps determine whether the Tripout is isolated or part of a recurring pattern.
Access denied messageDisplay text when a user without sufficient rights attempts to enter protected settings or when password rules are not met. ​Prevents accidental or unsafe adjustments and signals need for authorised access.
Manual reset procedureSequence of acknowledging alarms and resetting the controller once the fault is corrected. ​​Restores operation while ensuring that the underlying problem has been solved.
