Thetford Fridge Internal Circulation Fan

This genuine Thetford internal fan fits inside the fridge cabinet on Thetford's N4000 series absorption refrigerators, circulating air around the interior to even out temperatures and improve cooling performance, particularly useful in hot weather or when the fridge is heavily loaded. It's a direct replacement for a failed or seized original fan, and is distinct from Thetford's external ventilator/roof-vent fan kits, which cool the rear cooling unit rather than the cabinet interior.

• Thetford part number: 691729
• Type: Internal cabinet circulation fan
• Fitment: Thetford N4000 series absorption fridges, confirmed for N4141, N4175 and N4208
• Power: 12V DC (fridge auxiliary supply)

• Q: Is this the same as the fridge ventilator kit fan?
  A: No, Thetford's ventilator kits (e.g. part 630543) cool the rear cooling unit through roof/floor vents, while this fan sits inside the fridge cabinet to circulate air around the food compartment.
• Q: Which fridges does it fit?
  A: It's listed against the N4000 series, specifically the N4141, N4175 and N4208 models.
• Q: How is it powered?
  A: It runs off the fridge's 12V control circuit, the same supply used for the fridge's display and control board.
• Q: Why would I need to replace it?
  A: A worn bearing or seized motor will make the fan noisy or stop it running altogether, reducing cooling evenness inside the fridge.
