Quick answer
Do not run another drying cycle to identify a thermostat. Electrolux says a burning smell from a washing machine, washer dryer, or tumble dryer requires immediate unplugging and contact with an Authorized Service Center. If it is safe to do so, isolate the EWW51476HW from power, keep it out of use, and do not open the cabinet, measure live circuits, bypass a temperature control, or buy a thermostat from the model name alone. The official Electrolux parts page lists EWW51476HW with a PNC version of 91460490200 and requires the rating-plate PNC for compatible parts; confirm the complete product number and purchase market before any part discussion. Record when the odor began, whether clothes were unusually hot, any smoke/scorching or breaker trip, and the exact drying programme for the technician. A visible lint or residue clue may help service locate the fault, but it does not prove that the thermostat is the cause.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Stop the drying cycle and unplug the washer dryer immediately if there is a burning smell and the plug can be reached without touching a hot, damaged, wet, or sparking area.
Expected result: There is smoke, sparking, melting, scorching, a sharp electrical odor, unusually high heat, or a breaker trip, or the smell is simply clearly burning.
Next step: Keep the appliance out of use and contact an Authorized Service Center. If there is active smoke or fire, leave the area and use the appropriate emergency response; do not re-energize the machine.
Stop if: If the plug cannot be reached safely, do not move the appliance or touch damaged wiring; isolate it only through a safe, qualified route and arrange service.
Why this matters
Why: This meets Electrolux's burning-smell safety boundary; it is not a safe symptom to reproduce for thermostat diagnosis.
-
Check 2
Read and photograph the complete rating plate after the machine is safe, including the model code, 11-digit PNC, serial number, and market or language markings; do not rely on EWW51476HW alone.
Expected result: The plate confirms EWW51476HW and PNC 91460490200, shows another PNC, or cannot be read.
Next step: Give the exact plate information to Electrolux or the service provider. If the PNC is missing or differs, do not order a thermostat until the provider confirms the exact product variant.
Stop if: If the plate is inaccessible without moving or dismantling the appliance, stop at the visible information and let the technician identify it.
Why this matters
Why: Electrolux uses the PNC to determine compatible spares, and a market or PNC difference can change the documentation and part fit.
-
Check 3
Write down the drying programme, load, point in the cycle, odor description, whether the clothes or cabinet felt unusually hot, and any smoke, visible mark, noise, leak, error, or breaker event; do this without starting another cycle.
Expected result: The smell occurred only during drying, began at startup or later in the programme, followed an unusual heat change, or recurs with a fault indication.
Next step: Send this record with the model, PNC, serial number, and purchase or delivery date when booking service.
Stop if: If the timing is uncertain, report that uncertainty rather than recreating the symptom.
Why this matters
Why: Timing and associated observations help a technician separate the heating/air path, mechanical contact, residue, and electrical possibilities, but they do not identify a thermostat by themselves.
-
Check 4
After disconnecting power and waiting for the appliance to cool, inspect only visible user-accessible areas named by the exact manual, such as the door-seal area, detergent drawer area, and any applicable filter opening; stop if access requires force or a panel to be removed.
Expected result: Visible lint, residue, scorching, melting, water, or a damaged seal is present, or the accessible areas look clean.
Next step: Photograph the finding and leave the cabinet, heater, ducting, wiring, sensors, and temperature controls closed for qualified service. Do not run a cleaning or drying cycle to test the result.
Stop if: If nothing visible is found, keep the appliance isolated; a clean exterior does not rule out an internal fault.
Why this matters
Why: A visible finding can be useful service evidence but cannot prove the source of a burning smell or justify a thermostat replacement; Electrolux's filter layout is model-dependent.
-
Check 5
Ask Electrolux or a qualified appliance technician to diagnose the appliance and select any replacement only after confirming the rating-plate PNC and the failed component; do not buy a thermostat from a marketplace listing or a visual match.
Expected result: The service provider has the exact product identity, symptom record, and information about heat, odor, visible damage, and any code or breaker event.
Next step: Keep the washer dryer out of service until the provider gives a safe repair disposition; use only a part explicitly matched to the confirmed PNC if a part is authorized.
Stop if: If the provider cannot confirm the PNC or diagnosis, do not purchase or install the thermostat yet.
Why this matters
Why: The technician can assess the complete drying and electrical safety system and decide whether a thermostat, heater, wiring, sensor, airflow path, or another component is actually involved.

-
PATH 01Next step
What you see
Smoke, sparks, scorching, melting, a strong electrical odor, or unusually high heat is present.
Do this next
Disconnect power only if safely reachable, leave the appliance out of use, and arrange urgent qualified or emergency help as appropriate.
Why this path and its safety boundary
Why it matters: This is an immediate safety stop, not a thermostat-selection branch.
-
PATH 02Next step
What you see
The odor occurs during drying, but there is no safe visible clue after isolation and cooling.
Do this next
Do not run another cycle. Give the technician the exact programme and timing and request model-specific diagnosis.
Why this path and its safety boundary
Why it matters: An internal heating, airflow, mechanical, or electrical cause remains possible; the absence of a visible mark does not clear the machine.
-
PATH 03Next step
What you see
The rating plate is missing, unreadable, from another market, or shows a PNC other than the one listed for EWW51476HW on the UK parts page.
Do this next
Have Electrolux or a qualified service provider identify the product from the plate and confirm the part only after diagnosis.
Why this path and its safety boundary
Why it matters: Thermostat compatibility cannot be established from the short model code, and the public parts page is not enough to select a component.
-
PATH 04Next step
What you see
The smell persists, the appliance has unsafe heat, repeated interruptions, an electrical issue, or any fault returns after service.
Do this next
Keep it isolated and request qualified service; do not bypass temperature protection or continue troubleshooting by repeated operation.
Why this path and its safety boundary
Why it matters: Electrolux's repair guidance treats burning smells, unsafe temperatures, and recurring faults as reasons to stop use and book service.
Helpful context
Understand the symptom
Why a thermostat cannot be chosen from the symptom
A burning odor during the drying portion is a safety symptom, not a component identification. It can be accompanied by heat, lint or residue, airflow restriction, wiring damage, or another heating-system fault; the odor location and timing do not distinguish those parts safely. Electrolux's public instruction is to unplug a washer dryer with a burning smell and arrange authorized service. Treat the thermostat as a possible service diagnosis only, never as a part to select from EWW51476HW alone.
The exact product number matters
The official UK Electrolux parts page lists the model EWW51476HW and one PNC version, 91460490200, but tells the owner to use the rating-plate PNC to see compatible spares. Electrolux's manual-search guidance likewise identifies the model code and PNC as rating-plate data and directs appliances bought outside the UK or Ireland to the country of purchase. Therefore, verify the full PNC and market before asking about a thermostat; a partial model label or a different PNC is not enough to establish fit.
What can be observed without restarting the dryer
Once the machine is isolated and fully cool, limit inspection to visible, user-accessible areas described by the exact manual: the door seal, detergent drawer area, and any accessible filter or opening. Do not pull panels, reach into the heater or duct, scrape deposits, or make a test run. Electrolux's washer-dryer maintenance guidance is model-specific about filter layouts and says to use the user manual for the particular appliance. A clean visible area does not clear an internal heating or electrical fault, and a lint or residue finding does not identify a thermostat.
When checks do not resolve it
Need a professional?
Call an Authorized Service Center or qualified appliance technician immediately for any burning smell, smoke, sparking, scorching, melting, unsafe heat, breaker trip, repeated interruption, or recurring odor. Keep the washer dryer unplugged and out of use. Do not open the cabinet, test live circuits, bypass a thermostat or other protection, or run another drying cycle.
Common questions
FAQ
Which thermostat should I buy for an Electrolux EWW51476HW that smells burnt during drying?
Do not buy one yet. Electrolux says to unplug a washer dryer with a burning smell and contact an Authorized Service Center. Confirm the complete rating-plate PNC and have the cause diagnosed before any component is selected; the model name and symptom do not prove that the thermostat is the failed part.
Is PNC 91460490200 the thermostat part number?
No. The official Electrolux parts page presents 91460490200 as a PNC version for the EWW51476HW model. The PNC identifies the appliance variant so compatible parts can be checked; it is not a diagnosis or a thermostat part number.
Can I run an empty drying cycle to locate the smell?
No. With a burning smell, keep the appliance unplugged and out of use. Record the programme and timing from what already happened, and let qualified service inspect the drying and electrical systems.
