RELAY-START

When part 18-1903-62 is specified for a service call, the component involved is the relay start. It is commonly ordered when a machine still has power available but a specific circuit, movement, or cooling function is no longer working correctly. Confirm the equipment brand and the original part reference on the unit before installing a replacement. 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. Depending on the machine setup, failures in this part category can show up as compressor not engaging, clicking but not starting, and intermittent operation. 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. A good service approach is to verify the exact part number and inspect the surrounding assembly before replacing the component. For relays/contactors, check contact wear, coil continuity, terminal heat damage, and whether the load is drawing excessive current. Verifying the complaint under operating conditions before and after replacement is a practical way to confirm the issue is resolved. Once the failed part is confirmed, replacing it with the correct item can restore normal function and prevent ongoing intermittent complaints. For ordering, match the part number exactly and compare the removed component to the replacement before installation. That step matters on commercial ice equipment because similar-looking parts can have different ratings, connectors, or mounting details. If you are troubleshooting symptoms such as not turning on, no power, not cooling, not starting, intermittent operation, error code behavior, or ice not dropping, confirming the failed component first will make this replacement more effective.
