RELAY

The relay identified as part 18-8746-24 is a replacement component used during equipment repairs. It is generally replaced when the original part is worn, damaged, electrically weak, or no longer performing its normal function in the machine. Before purchase, compare the machine brand and the removed part markings to avoid ordering a visually similar but incorrect item. Where model references are available, cross-check the service model and revision level because similar machines can use different parts. Helps the circuit start and switch loads correctly when the machine is not starting, clicking, or short cycling. When this component fails, technicians may see issues such as clicking but not starting, intermittent operation, and compressor not engaging. Relay or contactor faults can interrupt startup and cycling, especially when contacts are worn or the coil becomes unreliable. For this relay/contactor category, the typical repair goal is to restore the function that the failed component was affecting. Before ordering, technicians usually confirm the part number, inspect adjacent components, and test the affected circuit or mechanism. Relay diagnosis usually includes continuity checks, contact inspection, and verification that the controlled load is not causing arcing or chatter. Verifying the complaint under operating conditions before and after replacement is a practical way to confirm the issue is resolved. Installing the correct replacement part can resolve the targeted fault path and helps bring the machine back to stable operation when the diagnosis is accurate. The best results come from matching the part number to the machine and replacing it only after the failure has been confirmed. Symptoms such as not turning on, no power, not cooling, not starting, intermittent operation, error code faults, or ice not dropping may point to this part category, but technicians should verify the complete failure path to make the repair stick.
