KitchenAid KFIV29PC Relay Valve Repair
For the KFIV29PC, also sold as the KFIV29PCMS, we first ask whether the top shelf is freezing food while the lower shelves run warm. That points to a cold control or thermistor that has drifted away from true, and we confirm it with a reference thermometer before replacing anything.
The inlet valve is the quiet troublemaker. A weep from it leaves a thin puddle behind the cabinet that is easy to miss until the flooring swells, so we look there on every visit. We also read the plate, which on this model shows KFIV29PCMS03, to order the right part.
If the compressor sits dead and nothing starts, the start relay can be to blame, because it can stop a mechanically sound compressor completely. We test it before discussing anything bigger. A cabinet that ignores its settings after many years may have a control board problem. The written price comes first, and our work has a 30-day workmanship warranty.
More likely a drifted cold control or thermistor is telling the control to keep cooling. We compare the real temperature with the control reading and replace the part that is wrong.
We pull the cabinet forward, dry the inlet valve and tubing, and run water through them while watching for a bead of moisture. Replacing the weeping part ends the puddle.
Not necessarily. A failed start relay is a common cause and a small part. We test it before looking further, so you only pay for what actually needs to be replaced.
