is a high-performance, compact reciprocating compressor designed primarily for commercial refrigeration and deep freezer applications. Known for its reliability in R290 (propane) systems, this 1/3 HP model is a popular choice for cooling commercial chest freezers, glass top freezers, and visi-coolers in the 300 to 350-liter capacity range. This article provides an in-depth look at the Go to product viewer dialog for this item.
Connect the meter across terminals R and S . The measured value must equal the mathematical sum of the run and start windings (
The mechanical core uses a traditional reciprocating piston mechanism. This ensures excellent durability, reliable performance under varying ambient temperatures, and the ability to pull down deep freezer temperatures quickly. R290 Hydrocarbon Optimization
If an appliance utilizing the L68WU1 compressor fails to cool properly, technicians should follow this structured diagnostic protocol. Diagnostic Matrix Potential Root Cause Verification Step Corrective Action Seized mechanical assembly or faulty PTC relay. Measure current draw during startup. Check PTC continuity. l68wu1 compressor pdf
Operating on an RSCR configuration, the compressor uses a 5 µF run capacitor to optimize the running power factor. This design minimizes electrical waste during prolonged run cycles, lowering the appliance's overall operating cost. Electrical Troubleshooting and Resistance Diagnostics
