HOW TO CORRECT |
| Blown fuse |
Check to see if fuse is OK. |
If blown, replace with fuse of
proper size. |
| Low line voltage |
Use voltmeter to check
pressure switch or terminals nearest pump. |
If voltage under recommended
minimum, check wire size from main switch on property. If OK, contact
power company. |
| Loose, broken or incorrect
wiring |
Check wiring circuit on
diagram. See that all connections are tight and no short circuits exist
because of worn insulation, crossed wire, etc. |
Rewire any incorrect circuits.
Tighten connections, replace defective wires. |
| Defective motor |
Check to see that switch is
closed. |
Repair or take to motor
service station. |
| Defective pressure switch |
Check switch setting. Examine
switch contacts for dirt or excessive wear. |
Adjust switch settings. Clean
contacts with emery cloth if dirty. |
| Tubing to pressure switch
plugged |
Remove tubing and blow through
it. |
Clean or replace if plugged. |
| Impeller or seal |
Turn off power. Using a
screwdriver, try to turn impeller or motor. |
If impeller will not turn,
remove housing to locate source of binding. |
| Defective start capacitor |
Use an ohmmeter to check
resistance across capacitor. Needle should jump when contact is made. No
movement means an open capacitor; no resistance means capacitor is
shorted. |
Replace capacitor or take
motor to service station. |
| Motor shorted out |
If fuse is blown when pump is
started (and external wiring is OK), motor is shorted. |
Replace motor. |
