What to do if my KRUEGER Fan motor will not run?
If your KRUEGER Fan motor isn't running, first check if there's 24VAC power. If there is power, ensure a fan speed is being commanded. This can be checked via jumper JP1, a unit-mounted or remote-mounted three-speed switch, or a thermostat.
How to troubleshoot no 24VAC power in KRUEGER A Series Fan?
To troubleshoot a lack of 24VAC power in your KRUEGER Fan, start by checking the onboard fuse (F1). Use a multimeter to measure the resistance across the fuse. A working fuse should measure less than 1.0?, while a blown fuse will show as an open circuit. Replace the fuse if it's blown, using the correct replacement. Also, make sure the incoming voltage to the unit is within the specified tolerance. Verify the unit is wired correctly according to the wiring diagram for the incoming voltage. Check that all wire harness connections are secure. Ensure either a float switch or JP2 is installed, and that the float switch (if present) is activated. Finally, confirm that either an external start/stop or JP3 is installed. If all these are confirmed and there's still no power, the transformer may be...
