we turn on projector, fan works, light comes on, fan is on high working properly, it runs for 6 minutes, then only the light goes off and the fan stays on (in high position) and within 1-2 minutes the light comes back on and runs for another 5-6 minutes and the light goes off again. Can the thermal switch be bad? We think unit is cooling properly.When turned on and then off fan runs in low position, working properly also.
