Checks and repairs on electrical components
Measure the current at 0 bar.
The regular current is 10.2 A ± 0.5 A at a pressure of 0 bar.
After approx. one second, the current has to decrease by about 2 A.
If the current does not decrease, the capacitor is defective.
If the capacitor is defective, replace it, see page 42.
To check the stator, proceed as follows:
Let the motor cool down to a temperature of about 25 °C/77 °F.
Check the temperature with a contactless thermometer.
Move the unit into the repair position for the electric control, see from
page 24.
Measure the electrical resistance of the main motor winding.
Measure the electrical resistance of the shunt motor winding.
