Motor
Overheating or Starter Tripping Out |
|
Possible Causes |
| What
To Do | |
|
High differential pressure |
| Check the motor's full
load amperage. Adjust the by-pass valve setting to a lower setting. See recommendations
for low capacity due to high differential pressure. |
|
|
Starter overload heaters too small | |
Check motor load with ammeter and confirm heater size with starter manufacturers
instructions. |
|
|
Low line voltage |
| Check line voltage when
in operation. Be sure motor is wired for the proper voltage. Check the electric
motor's nameplate. |
|
|
Motor shorted out | |
TEFC and explosion proof motors are subject to moisture condensation inside when
used intermittently. To eliminate trouble, allow motor to operate at least once
a week long enough for the motor to get hot. This would not be necessary during
off seasons when equipment is not normally operating. |
