Common failure areas on this model

The confirmed parts above group into a handful of failure areas. Here is what each points to and how to check it before you order anything.

General hardware and mounting parts

Symptom: A small mechanical or mounting part has failed, cracked, or gone missing.

Check: Compare the physical shape and mounting points to the original piece, and confirm the exact part number against your model plate before ordering.

Parts in this group on TH-42PA20U: 960010604002 (Bolt), 22196492 (Home Electronics Switch), 22223190 (Home Electronics Transformer), 105504 (Toro Hold Down Ro), TTEA01331 (Escutcheon), TXNPA1QCSU (PCB Assembly), TNPA2872 (PCB Assembly), TNPA2873 (PCB Assembly), TBMA138 (Badge), S1WBA80Z (Diode), K6B2ADA00007 (Relay), WR01X25808 (Plug Rvsbl B), ERZV10V621P2 (Varistor), WH49X10077 (Washer Shipping Bolt Kit), DD9401062A (Dishwasher Leak Detector Sensor), PC123FY2 (Integrated Circuit).

Storage, trim and cosmetic hardware

Symptom: A cracked shelf, broken door bin, worn hinge, or missing trim piece -- cosmetic and storage wear rather than a functional breakdown.

Check: Match the physical dimensions and mounting tabs of the old part before ordering; these pieces are often model-specific even between visually similar models.

Parts in this group on TH-42PA20U: TXND10QCS (Panasonic Pc Board), TXNK1QCSU (Panasonic Pc Board), 7075836 (Snapper Housing), ERZV07D361 (Panasonic Diode), 75306848 (Line Trimmer Cutting Head Assembly).

Controls, timers and wiring

Symptom: A cycle that doesn't advance, an unresponsive display, or the unit not starting at all.

Check: Look for burn marks or a burnt smell near the board or terminals, and check whether buttons and knobs respond -- a unit that powers on but won't cycle often traces back to this group.

Parts in this group on TH-42PA20U: TNPA2958AB (Panasonic Scan Drive Control Board), WB27X10935 (Microwave Electronic Control Board).

Before you buy

Match TH42PA20U exactly against the model and serial plate on the appliance itself before ordering anything — a single mismatched character can point to a different production run with different parts. Then check the part number printed or stamped on the part you are replacing against the part numbers in the table above; the printed number is the most reliable way to confirm fitment when a model has gone through multiple production runs. RepairKitHub does not sell parts directly — every part link above routes to an Amazon search for that part number so you can compare current listings and sellers yourself.

How to confirm this is your model

Check inside a door opening, on a back or side panel, or behind a removable panel or drawer for a label printed with the model and serial number. Match every character exactly, including letters and dashes at the end — appliance model numbers often have similar prefixes but different suffixes for different production runs.

Still not sure?

Use the model lookup tool to search by model or part number, or start from the symptom your appliance is showing.
