Hello all
Our Omni 5 has given the 'Cooling module high temp' warning twice during the past month. I suspect that the blower motor is the culprit but have not been able to verify this because the oven has started up normally after acknowledging the error. Anyway, after the first alarm we cleaned the blower motor thoroughly but obviously it did not help because the alarm came back a month later.
So could it be the overtemperature sensor giving false alarms? Does anybody know where this sensor is situated (have not been able to locate it in the documentation)?
I do not relish the idea of ordering a new blower assy because the fault may not be there. Especially, as Speedline only sells the complete blower assy at over 1600 � ...
Is it possible to bypass the overtemperature sensor if the fault should lie there or if the motor fails permanently? As far as I know, the function of the cooling blower is only to cool the PCBs exitting the oven so is there a risk if I try to run the oven with the cooling fan disabled? The idea is just to keep the line running while waiting for spares from Speedline, not as a permanent solution.
Also, I do not know about the exhaust air temperature if the cooling fan is not working, maybe I'll be blowing air at 250�C into the exhaust stacks which may not be such a good idea after all...
