Camray 3 motor capacitor

[simonlambard]

Don't replace the boiler unless it' leaking water, that's just an incompent service technician's approach. Check the value of the motor run capacitor. I bet it's less than 3uF, and it should be near 4uF. These boilers are ok, and spares are easily available.

The buzzing is the motor can't start because there's not enough torque from the capacitor.

Hi Oilman

Would you buy any chance have a part number for the capacitor for the Camray 3 and as the boiler is so old are they hard to soure.

Thanks in advance

Original part No was 3005798, and it was called a condenser, still a capacitor though.

Thank you for your help, I am hoping its the condenser as the pump/fan tries to spin but cannot, but will with some help.

Thanks again

It's called a CAPACITOR, it's an electrical component. A CONDENSER is used on steam systems to, er, CONDENSE.

Capacitors were also known as condensers.
Modern term is a CAPACITOR



"Condenser" still designates the rotating synchronous machine used to supply leading kvars in a power circuit (a function of which capacitors are also capable), because unlike a capacitor, the synchronous condenser cannot store energy electrostatically; it lacks the property of "capacitance." For the non-rotating device, however, capacitor is the proper term.

If Im not mistaken (probably am) I think the yanks still call capacitors condensers

When I worked for the CEGB I thought it was known as a synchronous compensator and it was used to remove excess Mvars from the system. It was an effing great motor run up to speed and then left sitting on the system doing its job.

Steam turbines can also be run up to speed, synchronised to the Grid and left in compensating mode.

Replaced the Capacitor and filters and alls fine again. thanks for all your help.

Really got me out of trouble, unable to get an engineer until the 5th

And Sorry for the Hi Jack new to forums
