Common service complaints can include control issues, short cycling, and temperature drift. If the thermostat is worn or failing, replacing part WPF33A can restore the affected function. Confirm the root cause first so the replacement actually solves the problem. After replacement, run a full operating cycle test and recheck for leaks, vibration, or returning symptoms. Compare the removed part to the replacement for connector style, mounting points, and orientation before installing. When you’re ready to replace the part, finish with a careful install and test. Install the thermostat carefully, then verify operation after replacement. Using the right part number helps solve the fault cleanly and improves repair confidence. Inspect related components so the new part isn’t exposed to the same stress that damaged the original. After the first test cycle, recheck fasteners and connectors to confirm everything remains secure. Inspect related components so the new part isn’t exposed to the same stress that damaged the original. Keep the removed part nearby for a side-by-side comparison during installation. Document the symptom and the post-repair test result for future service history. Inspect related components so the new part isn’t exposed to the same stress that damaged the original.
