Troubleshooting

Use the information in Table 7 to troubleshoot the flow
switch.

Repairs and Replacement

Do not make field repairs, except for replacement of
the cover and paddles. For a replacement flow switch,
paddle kit or cover, contact the nearest
Johnson Controls/PENN™ distributor. For more
information, contact Refrigeration Application
Engineering at (800) 275-5676.

Table 7: Troubleshooting

Symptom/Problem

Solution

Water (condensate) is within the enclosure.

Use a model with a NEMA 3R enclosure. If using a model with

a NEMA 3R enclosure, inspect the grommet in the conduit

fitting. Replace grommet if defective.

Fluid from the tank is leaking into enclosure due to

bellows failure.

Replace flow switch.

Switch does not activate due to debris caught within

the switch mechanism.

Clear any debris within the switch mechanism. Test the

operation of switch several times for proper operation.

Control switch action is reversed.

Ensure connections follow wiring diagrams.

Control does not switch.

Check connections.

Switch fails to return to the no flow position.

Switch is set lower than the factory setting. Increase the setting.

On vertical pipes, ensure that direction of flow is up. The arrow

on switch must point in direction of flow (up).

Control does not switch on flow increase.

Check for cracked/broken paddle. Replace if necessary.
