As you are probably aware, the fans for the white knight dryers are no longer available. Have found a compatible replacement from Maddocks an alternative fan 102-CS-3983 for Crosslee White Knight CL4, CL5, CL6, CL7; Bosch WTA2000, WTA3003; Siemens WT2100; Philips Whirlpool AWB, AWG Series. They are as good as the original and fit well.
