Understanding the Problem

You supplied a serial number (TH73412518). A serial number by itself usually does not tell you what part is failing — it’s used to identify the exact model, manufacture date, and warranty status so you can get the correct parts and service info. Follow these steps to turn that serial number into actionable repair information and, once you have the model, how to proceed with diagnosis and repair. 1) Locate the model tag and serial tag on the appliance - Check common tag locations: inside the door or door frame (washers/dryers/dishwashers), on the back panel (refrigerators/ranges), on the left or right door jamb, or behind the toe kick/panel. The tag will show both MODEL and SERIAL—model is the key to parts and manuals. - If TH73412518 is the serial, note the MODEL number next to it (example formats: WTW5000DW, KRMF706ESS, etc.). 2) Decode the serial (optional but useful) - Some manufacturers encode manufacture date and factory in the serial. Use the manufacturer’s serial decode reference (search “[brand] serial number lookup” or contact support). This can tell you age (important for warranty and for expected failure modes). 3) Find the service manual and exploded parts diagram - Go to the appliance manufacturer’s official parts page and enter the MODEL number (not the serial) to get exploded views and part numbers. - If official site is missing info, search aftermarket parts sites (PartSelect, RepairClinic, AppliancePartsPros) by model number or use Google: “MODEL number parts diagram”. 4) Confirm the symptom and check common failure points - Identify the actual problem you are experiencing (won’t start, no heat, won’t spin, leaks, noisy, etc.). Use that symptom plus the model to find common failed parts for that model. - For example: washers commonly fail drain pumps, door locks, or control boards; dryers commonly fail heating elements, thermostats, or belt; refrigerators commonly fail evaporator fans or start relays. 5) Order the correct parts - Use the exact part numbers from the exploded diagram for your model. Do not order by symptom alone — many models use the same-looking parts with different connectors or firmware. 6) Basic step-by-step repair workflow (once you have model and parts) - Turn off power: unplug the appliance or switch off the breaker. For water appliances, shut off the water supply. - Access the failed component: remove panels following the service manual instructions—keep screws and note wire locations or take photos. - Replace the part: swap old part with new, transfer any brackets or connectors, secure fasteners to original torque, reconnect wiring harnesses exactly as removed. - Test: reapply power (and water if applicable), run a diagnostic or a short cycle to confirm repair. - Reassemble: put panels back and verify normal operation. 7) When to call a pro - If you can’t find a model number, if the repair requires sealed-system work (refrigerant), or if you’re uncomfortable with live-voltage work, call a certified appliance technician. Safety note: Always disconnect electrical power before working on an appliance. For water‑connected appliances, shut off water supply and drain hoses. If in doubt, consult a professional — repairs involving gas, refrigerant, or high voltages present serious hazards.

Common Symptoms

None from the serial alone. A serial identifies the unit so you can find model-specific symptoms, parts diagrams, and common failure modes for that model.

Common Causes

  • You only have the serial and not the model number, so parts/manual lookup is blocked.
  • The tag is missing, damaged, or located in an unexpected place.
  • Different models share similar-looking parts but have incompatible connectors or firmware, so model-specific identification is required.

Helpful Repair Tip

Serial numbers identify the unit, but the MODEL number is what you need to order parts and find diagrams—look for the label that lists both MODEL and SERIAL, then search parts by MODEL.

Frequently Asked Questions

Can I use the serial number TH73412518 to order replacement parts?

Not directly. Serial numbers identify the specific appliance but parts catalogs and exploded diagrams use the MODEL number. Use the serial to find the model (on the same label), then search parts by MODEL to ensure compatibility.

I can’t find a model number, what should I do?

Look in less-obvious places: inside the door/frame, on the back panel, behind the kick plate, or under the lid. If the label is missing or unreadable, contact the manufacturer with the serial and a photo of the appliance — they can often identify the model from the chassis and serial. If still unsure, a service technician can verify the model and recommend parts.
