AEG, Electrolux & Zanussi Tumble Dryer Belt Tension Roller Parts — Models & Compatibility

If your AEG, Electrolux, or Zanussi dryer is making squealing noises or the drum isn't turning smoothly, the belt tension roller (also called a jockey pulley) is often the culprit. This guide covers the 1250125034 replacement roller, which fits dozens of models across these three brands and replaces older part numbers 1250125000, 1250125109, and 8581250125037.
Is This the Right Part for Your Model?
Check your dryer's model number — it's usually on a metal plate inside the door frame or on the back panel. If you've got an AEG LTH series (like the LTH57800 or LTH59800), an Electrolux EDC series (EDC46100W, EDC47100W), or a Zanussi dryer using this belt system, this tension roller should fit. Cross-reference your exact model against the compatibility list below to confirm.
About This Replacement Part
The tension roller keeps your dryer belt tight against the drum and motor pulley. When it fails — either the bearing seizes or the wheel cracks — you'll hear squealing, grinding, or the drum may stop rotating altogether even though the motor runs. This roller is a direct OEM-compatible replacement that restores proper belt tension and quiet operation. At $15.99, it's significantly cheaper than a service call, and most DIYers can swap it in under an hour with basic tools.

What You're Replacing
This part supersedes and replaces the following older part numbers:

- 1250125109
- 8581250125037

Installation Overview
You'll need to remove the dryer's top or front panel (depending on your model), release the old belt from the motor pulley, remove the worn tension roller from its mounting bracket, install the new roller, and re-thread the belt. It's straightforward but requires some maneuvering. Take photos as you disassemble — it'll make reassembly much easier.
Why This Part Fails
Dryer tension rollers run constantly whenever the drum spins, under significant load from belt friction. Over time, the bearing wears out or the plastic wheel develops cracks. High heat and lint buildup accelerate the wear. If you're replacing this roller, inspect your belt too — if it's frayed or cracked, replace both at the same time to avoid another repair soon.
