94pt 'cool o matic' gally exhaust fan

[Gregory OConnor]

Leroy, now you did it, we were headed out to VeraCruz for fish now I
want steak. I removed the speed control and hardwired the fan under
the cover so now it only runs at full speed. I dont believe the
wire to the fan passes the thermostat?? I know changing voltage to
the relay wont adjust the fan but for a steak dinner, Im game

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.

be drawing too much amps and the reason some issue of power faulted
in one of the fuese, relays or potentiometer.

I dont know how to measure amp draw). My fan has a lable that says
8 .5 amp full speed.

relocate the potentiometer to the thermostat wall.
