94pt 'cool o matic' gally exhaust fan - Ron Hazlett - 09-30-2008 11:52

If anyone has removed their cool-o-matic Fan cover and has no use for
it. I would be happy to purchase it from them! Mine was damaged by a
falling tree branch.

Mine also has Green, Brown, and White. Green-to-white turns the Kool-o-matic on,
Brown to white is the heater.

I replaced with a Hunter 42999B from Wal-Mart, digital. Green to the G terminal,
Brown to W, White to Rh, with a jumper from Rh to Rc. Y has no connection.

Works very, very well.

Dick,

I appreciate the offer -- but I'm about to start moving the rig more
frequently, so I don't have an address where I can receive the stuff
-- at least not until January.

Thanks.

Ron,

Go ahead and work with Dick -- I'm not in a position to receive a
unit -- and I'm not sure that my cool-o-matic is actually dead, since
I'm not getting power to the fan.

Good info!! Just what I needed to know. If I can find a Walmart in
this state, I'll take a look at the Hunter thermostat.

Wal-Mart carries many Hunter thermostats, so look at them closely, as many would
not be suitable for the purpose. The 42999B may be the only one, in fact.

94pt 'cool o matic' gally exhaust fan - Gregory OConnor - 10-01-2008 03:34

The thermostat output wires probably doesnt even power the fan. most likely it powers a bosch relay.

  • there is a fuse for the thermostat power (above driver sk10) this power wire to the thermostat is green
  • and a fuse for the fan relay power (above driver sk10) power wire is orange/black.
  • The fan relay switch (K8,a bosh relay above driver) gets a 12v signal from the thermostatfixture to send another source of 12v power power(sk10) to the fan
    • [/list]


    The thermostat sends a signal back to the relay above the driver. that signal causes the relay to make contact and connects the sk10 fuse to the fan. the potentiometer at the fan then dictates the speed. for the fan to work both fuses the relay and the potentiometer must check out ok.



    you can test the fan inplace by hooking it up to a portable carbattery jump pack. if it runs it still may not be good, could be drawing too much amps and the reason some issue of power faulted in one of the fuese, relays or potentiometer.



    an ampmeter between the battery and the power should prove draw ( I dont know how to measure amp draw). My fan has a lable that says 8 .5 amp full speed.



    since the fan is not powered directly by the thermostat I can not relocate the potentiometer to the thermostat wall.

    Greg,

    More good info... I thought I saw an orange/black wire going to the
    fan motor -- that explains where it comes from. I'll have to spend
    more time studying the overhead fuse panel -- I don't have a
    schematic of that one, so it's been a little hard to see what is what...

    Ron,
    The cover is available if you want it. No cost, just pay the shipping and it's yours. I must tell you though, the rear corners have both cracked some. Not enough to ruin it and could be repaired with fiberglass. Certainly better than one that has been smashed by a tree.
    Same deal as with Pete, we will be leaving soon so let me know.

    If anyone has removed their cool-o-matic Fan cover and has no use for
    it. I would be happy to purchase it from them! Mine was damaged by a
    falling tree branch.

    94pt 'cool o matic' gally exhaust fan - Robert Akins - 10-01-2008 05:18


    Have any of you contacted Kool-O-Matic. Their web site is
    They no longer manufacture systems but still provide spare parts. I recently bought a replacement motor and speed control from them and everything worked like new.
