Powertech 15kw cooling fan

[Pete Masterson]

Just got back from a trip to Oregon. The cooling fan on my Powertech
generator seems to have quit working.

In the few days before the failure, I was noticing a very serious
(but transient) amperage draw on leg one accompanied by dimmed lights
in the coach. These lasted from one-two seconds up to about 10
seconds (infrequently). At first, I suspected one of the AC units --
but the problem didn't occur on shore power.

Finally, the generator would run for 20 minutes or so -- then just
quit-- with the water temp gauge showing a high temperature. After
allowing an hour of so for cool down, the generator would start up --
and run for awhile until the temperature got too high again.

The water is full up (as it has been). Oil is OK -- and so on.

However, the fan simply doesn't cycle on.

I searched the archives -- but there don't seem to be specific
discussions of what to do when the fan simply doesn't work. (I'm
guessing I have to replace the fan motor.)

Any comments and suggestions where to get a replacement fan motor?

The first thing that I would is check that there is power to both legs to the
fan motor.If both legs are hot then I would guess that the motor is bad.When I
replace my motor
I got it from Granger.

I replaced my fan motor a year ago. You can purchase a replacement at
any good appliance repair company. It is a 220v motor. You might
have to modify the rubber mountings in the brackets. It is difficult
to remove the fan from the shaft. Soak it well and place the fan on
wood blocks so you can knock the motor shaft out of the fan.

When you replace it, make sure to balance the motor & fan. There are
small metal clips on the fan blades used to balance it.

Pete,

If your gen. fan set up is the same as on the 87 PT, which looks like the
fan unit for the house furnace, take the whole unit out and take it to a
motor shop (AAA Electric Motors in Anaheim is where I took ours). I paid
$158.58 for a new motor, clean/paint the housing, new fan/balancing, new
capacitor.

Indeed, it sounds much the same. I like this idea. I'll check around
for a similar shop in this area.

Is the fan motor getting voltage? If so you are sure its the motor can you have
it rebuilt?

most likely your fan motor is gone, I just recently replaced mine, 95pt 40
not bad for 12 yrs, a replacement motor cost me $55.00, it is the same motor
used on residential ac units, grainger was almost twice as much, check out your
local ac supply house
