- buy a 1.5kW single phase motor with the correct shaft / pulley and fit it. Check that the previous repair has actually provided single phase power (with neutral) and isn't running the motor across two phases | - buy a 1.5kW single phase motor with the correct shaft / pulley and fit it.

Things we've checked : | |||
Looking at the motor connections on the cover diagram, it's apparent that mains power must flow into V1 for any effect at all. But this connection has a high resistance to all other pins. It's either a burnt out winding, a faulty switch (unlikely, given the connections) or unused wiring (seems surprising, but there are too many wires for a simple single-phase capacitor-run motor). | |||
The capacitor appears to be fine | |||
Things we haven't checked : | |||
There is a wiring diagram on the Tec website for capacitor-run motors which does not use the unconnected V1 pin. Perhaps this is the correct wiring ? But then how did the motor ever work ? | |||
