Heating

Motor seems dead, mentar took it apart and connected it to the mains to make sure it was the motor that wasn't working, which was confirmed. Drop box photos


The motor is a bit of a puzzle :

Old wiring appears to be three-phase, but the current motor, which looks fairly new, is single-phase.

The motor is numbered 1.541TPCB3, which doesn't appear to correspond with the parts listed at http://www.tecmotors.co.uk/ though TPC is one of their designations.

The exact same motor is listed at http://www.engineersmate.com/products/SINGLE-PHASE-MOTORS-230V/1-5KW-4-POLE-FOOT-MOUNT-230V-1PH-PERM/P239654

The wiring diagram inside the connection cover appears to show a capacitor-start motor with a centrifugal switch, but there is no obvious switch. It would be reasonable to assume some of the internal wiring is to a switch, but the connections shown are open circuit. Furthermore, if they were to a switch, it would turn the motor off once it got to speed.
