    The bearings in the cooker side fan run dry and seize. I have tried lubricating with clock oil, motorcycle chain lube and moly grease. Each time the motor runs well for 24 hours then seizes again. The central heatig side fan runs perfectly well. What is the technique for relubricating the sintered bearings please?

    If they are sintered bronze bearings, the norm is to soak them in oil for 24 hours before installation. Under pressure is even better.
    If the motor is continually seizing, it suggests to me that the bearings are worn out.

    I doubt if you will get a new unit for one of these cookers, but some places offer a reconditioning service. Contact www.abgo.co.uk for advice.
