KitchenAid KRFF507H Relay Fan Service
A KRFF507H, also sold as the KRFF507HPS, that clicks every few minutes and never cools is telling us the start relay or overload protector has stopped doing its job. The compressor is usually fine. We test both parts with a meter and replace only the one that fails, which keeps the repair small.
Electronic complaints come next. A panel that goes unresponsive while the cabinet keeps running points us at the control board and its harness, and we examine connectors for corrosion before deciding whether a board is needed. This model has been discontinued, so we check part availability as part of the quote.
Mechanical checks complete the visit. An evaporator fan with worn bearings will not start from cold, so we spin it by hand and listen. Condenser coils coated in dust and pet hair force the compressor to run longer and hotter, and cleaning them helps every cabinet we see. A written price comes first, and our repair carries a 30-day workmanship warranty.
The start relay is trying to start the compressor and the overload protector is cutting it out. We test both with a meter and replace the one that is weak instead of the compressor.
Often. We check power to the panel, the harness and connectors, then the control board. If a board is needed, we confirm that one can still be obtained before quoting.
Lint on the condenser coils holds heat in. We brush and vacuum the coils, make sure the fan turns freely and leave the airflow clear so the compressor can cycle off sooner.
