Troubleshooting Guide

Symptom: Electric fans do not turn on (start) at selected “On” temperature: Thermal Sensor May Not Be Functioning; check the wire between the sensor and control unit for cuts, pinches or slices by fan blade or other cause. Replace sensor assembly.

Symptom: Only one electric fan works: Check and replace relay between the control unit and the second fan.

Symptom: To test to verify that both fans work: Energize blue wire; both fans should run.

Symptom: Fan blade “rattles”, is noisy, or is loose on motor shaft. Secure fan blade assembly with silicone caulk:

1. Carefully remove the fan clip on the shaft by sliding it off slowly with a knife or thin tool.

2. Take a long flat head screwdriver and slide it between the bearing housing and the hub on the fan blade making sure you slide the screw blade alongside the roll pin twisting the screw driver to force the hub off the shaft, make sure it is parallel as not to break or damage the pin, shaft or blade. Warning! Be sure not to put it under the roll pin, you want it parallel to the notch alongside the pin. Slowly slide the fan blade off shaft.

3. To reinstall the blade we recommend that you put a small amount of silicone caulk on the shaft, notch and hub. Then slide the blade back on to the timing roll pin with the notch in the fan blade slid onto the timing roll pin.

4. Use a new blade-retaining clip (or gently flatten existing clip). Press clip down onto shaft into place against blade. Use a 3/8" socket to cautiously press clip into place against blade, then lightly tap with a hammer or similar tool to seat.

5. Set the fan aside to let the silicone completely cure according to product specifications. Your Cool-Pack™ is now ready to reinstall on your vehicle.

Symptom: Fan motor “pulsing feel” when blade assembly is rotated by hand: Nothing is wrong with motor. Perma-Cool® electric fan motors feature very strong motor magnets, the “pulsing feel” is normal.

Symptom: Fan motor “locks up” when blade assembly is rotated by hand: Internal components may be loose, return unit to Perma-Cool® for inspection.

Symptom: Fuse holder melted: Replace fuse holder and install 40 Amp fuse. Recommended fuse is a 30-40 Amp fuse for start-up protection in all Cool-Packs™.

Symptom: Fans will not shut off. The controller relay contacts are probably sticking. Remove fuse, allow to cool (cycle down), then re-install fuse. If the fans turn on immediately (or if motors are off and the problem re-occurs), possible defective controller module. Send for service or purchase replacement controller #21006.

Symptom: Only one fan is functioning correctly: Secondary relay may be bad. Replace with a 5-pin, 40A 30/40 12V DC standard automotive relay, or purchase replacement relay #19002.

Symptom: Fans do not turn on with temperature probe, but do when AC is turned on or BLUE wire is energized.

1. Sensor probe may have backed out of radiator core: Re-insert/install probe into radiator fins.

2. Check for cuts in probe lead wires. Replace controller module if any are found.
