(1/2) > >>

slovakia:
I was buy very old hot tube ( year of production is 1996  :) but it is made in USA  8) ) I make little maintenance and all running very well just water pump motor overheating.

Please what is standard temperature of running electric motor.

I check it by laser thermometer on flange (bearing place) 64C and 75C but on the body in the midle is 93C.

Please it is corect?

Jacuzzi Jim:
 At 150f to 160 that us running pretty hot.  Does the internal switch shut it off, or does it keep running?

Tman122:
If it is running hot (there are a ton of variables that determine what is to hot) it should throw a breaker before it burns up.......assuming it is on a proper GFCI

slovakia:
Jacuzzi Jim: On the motor plate is information about thermally protection but never switch off it is overheat but running.



Tman122: Yes i have GFCI (current protector) 30mA but never switch off.

Jacuzzi Jim:
 Yeah like Tman said a lot of variables there as to why it's over heating.   It looks pretty old?  I'd say you have 2 options, run it as is till it dies. Which guessing won't be long.
 Or I would replace it.  No idea price wise where your at, but it would be your best bet.
