troubleshooting Section

The following troubleshooting guide is designed to help identify and resolve any operational difficulties that may arise with the PP-1808-1812-1816-44-V2. While performing the tests and checks outlined below, carefully inspect the machine for loose components, broken or loose wires, and poor electrical connections. It is essential to check switches, controls, relays, transformers, and other electrical components thoroughly. When diagnosing electrical issues, always use a voltage meter.

Important Notes:

• Use extreme caution to avoid the risk of electrical shock. Only apply power when necessary for voltage checks, and disconnect power immediately when it is not required.
• Always refer to the electrical components placement sheet and schematic diagrams to aid your troubleshooting efforts.
• DISCONNECT ALL POWER BEFORE MAKING ANY REPAIRS.
• Refer to the Electrical Board Layout and Electrical Schematic Diagrams for the precise location of electrical components

Make sure air velocity knob is not on low

Open main electrical panel. Check Blower Motor fuse F-1 (.5 AMP). Test fuses F1, F2, F3 and F4.

Check to make sure no air holes are obstructed due to plastic build up covering air holes.

Check main blower motor and replace if necessary. Check motor start capacitor (M2) to see if burned. Check rotation of motor. Compare with arrow direction and make sure motor is turning in the same  direction. Check motor wires 7 and 10 for loose connection. Check for 220-volt power across wires 7 and 10 (motor wires). If voltage is present and the motor still does not operate, replace motor.

Check motor contactor.  Check OL-1 motor overload contactor. Factory setting 5.5 to 6.0.

Check to make sure blower wheel is not loose on the blower motor shaft.
