A slow‑heating oven usually means a faulty element, temperature sensor issues, or heat escaping from the door.
Common causes
- Faulty heating element
- Damaged door seal
- Temperature sensor issues
- Too many trays inside
1. Faulty heating element
If one element fails, heat rises slowly.
Quick fixes:
- Check if the oven heats unevenly
- Look for dark or burnt spots on the element
2. Damaged door seal
Heat escapes around the edges.
Quick fixes:
- Inspect the rubber seal
- Replace if cracked or loose
3. Temperature sensor issues
A faulty sensor misreads the heat.
Quick fixes:
- Restart the oven
- Avoid touching the sensor
What to try first
Check the door seal — it’s cheap and easy to replace.
