You can measure the resistance of the motor coils to discount theose being burnt out. It takes a few seconds for a multimeter to stabilise at a reading

The 3 pins Common, Start and Run.
S-R (6K ohm? ) highest reading through both coils.
C-S (4K) resistance of Starting windings
C-R (2K) resistance of Run windings
Any pin to Earth should be open.

They're reading much lower - 22/45Ohms. I Guess this means the motor's screwed?

No, thats probably OK if you have 22, 45, 67

My mistake adding KOhms as that would be very high for it. It's a while since I measured ones on our dehumidifier and much longer back for the fridge or works aircon.

huh, seems more like 22/22/45

Worth giving the new relay a back for £13 from ebay do you think?

Sounds like I'll get a depreciated credit note from Currys, but it'd save a lot of hassle just not having to move it through my hall again.

You've got a resistance on each coil (not open or shorted) and also the sum of the two, so that stacks up.

With ebay returns massively siding with the customer, its certainly worth it.
