Troubleshooting Guide e. Check the input voltage to the transformer using a standard lead and a multimeter. Check the voltage from the black lead on the terminal L speed control switch and white lead on power supply board labeled line neutral. Activate the interlock switch. The meter should indicate line voltage. Check the voltage on the two yellow wires on the power supply board from the transformer. The interlock switch must be activated. The meter must indicate 24 vac. BLACK LEAD YELLOW WIRES WHITE LEAD If there is no power to the transformer, recheck section 1, the interlock switch. If there is power to the transformer, but no output voltage, replace the transformer and power supply board assembly. 3. If the green "cleaning air" light operates and the blower wheel does not turn. a. Remove the top and check to see if the stripper is in place. The stripper is held in position by slots in the contact wall and bearing plate and alignment tabs on the stripper plate. If the stripper is not in position, reposition the plate by placing tabs into the slots. b. Use your hand to try to spin the blower wheel. If the wheel does not spin freely, check for anything that may be blocking the movement of the wheel and remove the blockage. If no blockage is apparent, see 3c and 3d c. Turn the unit over and check for signs of distortion in the cabinet bottom beneath the motor that might prevent the blower from spinning. If the cabinet bottom is distorted, replace the unit. 9
