When you need Sensor, ordering by part number 1851701600 helps ensure you’re matching the correct listing. If the machine is showing timing errors, inspect this area for looseness, corrosion, rubbing marks, or a part that’s shifted out of position. If the problem changes with vibration or after moving panels, look for borderline fitment and loose connectors in the same area. Sensors and probes feed signals used for timing and safety. Incorrect readings can cause short cycling, nuisance shutoffs, or inconsistent output. Disconnect power before service. Reinstall carefully so nothing pinches, rubs, or binds once the unit is back together. Replacing the correct part helps restore predictable operation and reduces repeat service calls. Take a photo before disassembly so you can confirm orientation and fastener locations during reassembly.

If the part interacts with water, do a leak check during the first run and again after a short operating period.
