- Question Title: Kaeser SK26 over temp alarm

Cas,
Love your site! I tried to sign up but kept getting message that something went wrong.
We have a Kaeser SK26 rotary screw compressor that has been intermittently shutting off with a EXCESSIVE TEMPERATURE ALARM.
According to the service manual this occurs when the air end temp. exceeds 230 degrees F. And that is exactly what is happening.
Until recently the unit was always operating in the 150-180 degrees F. range but now
runs closer to 210 degrees constantly, with occasional alarms.
- The unit was recently serviced with new filters, oil, belts, etc.
- The ambient intake air temp. is less than 75 degrees F.
- The cooler is relatively clean and unobstructed
- No blockage of venting to the outside
Can you advise what might be the cause of this problem?
Thanks

Hello Wayne,
Thanks, I do my best to help as much people with their air compressors as possible :) The signup and login problems are fixed now!
I live in a Celsius world :) , so
Your previous running conditions sounds about perfect, so there must be going someting wrong indeed..
Did the problems start directly after the service? Was the correct type of oil used?
Please also check if there is no obstruction in oil flow somewhere (a pipe, valve, etc). You can try to find this by measuring the temperature at several points (element out, separator vessel, oil filter, supply of oil to element). If there are very big temperature differences, this could indicate a blockage somewhere.
Try to turn the motor/compressor element by hand when it is shut down (completely shut down and disconnect power source!). You should be able to turn it by hand, without any 'high points'.
Hope this helps!

99% is a thermostat problem , check if your cooler is warm or not
Thank you airend. You are right, I completely forgot about the thermostat. That must be the problem!
Thanks, Cas
