Sir Bowmeat . . . . . . ( and pray tell me . . . . WHAT is (a) bow meat ? )
You say . . . .
1 . . . . .The new fan is now working .
2 . . . . . But it only starts with a clicking noise like a relay from a car .
So now, in my working with ONLY those two minute snippets of info , I will have to interpret that as being that the motor and fan are working . . . . but that working is not being a CONTINUAL and steady running of the fan, but in mere bursts of rotation.
And that should be due to . . . . as your hearing suggests . . . . that the motor is MOMENTARILY receiving bursts of 220VAC voltage from a power relay that is pulsing on and off. Likely due to a fault in the system.
AND with my not being able to find not even a trace of technical service info on a Russell Hobbs microwave . . . .a pic off the basic control board of another brand of unit will have to suffice to point out a component to check out.
As the most honnable "duke-ster" infers,just above, the overloading effect of a fork being in the microwave cavity may have had ill effect upon the "RF generator " . . . . . .aka . . . . a HIGH power magnetron.
If that is the case . . . . . of an overload of that section . . . . you might now refer to the photo provided below and take note of the botttom left corner of this units control board and its power transformer, and then the MAIN point of interest would be the BLACK power relay located just above it.
Unlike the other string of relays on a board THIS one has HEAVY DUTY push on male connector blades mounted just above the actual internal heavy duty relay contacts.
In that construction, one gets a very short run . . . . . equalling . . . . . low power loss plus highest current capability.
That plug in connection is what powers the power magnetron !
So o o o o o o o . . . . . if you carefully use upward pulling and a slight screwdriver tip leveraging up at the bottom edges of that connector pair, it should unplug.
Leave it unplugged , aside, and free of touching any metal, and then power up the HOBBS for a short 10 second ? test duration to confirm that that the cooling fan then runs and there is no clicking , that the time cycle clock advances and the microwave shuts off after its short test time cycle .
If so, then the new cooling fan is OK and I am suspecting it to be so. Then fault is with the hi ppower magnetron circuitry . . .cycling on and off.
IF the magnetron is bad . . .THAT is when you THEN throw in the towel . . . .economically speaking.
EQUIVALENT MICROWAVE CONTROL BOARD COMPONENTS FOR COMPARISON . . . . .

My neighbor has just built himself a circular driveway . . . now he can't get out.
