Power Pack Assembly for White-Rodgers WW Series (NLA)

White-Rodgers Electro-Air Cross Reference

White-Rodgers equipment is identified by a model number. Replacement parts can be ordered based on the model number. Current model numbers are in the format SST1400-151, previous SST model numbers were 14c26s-010. See the Model Number Cross Ref for more examples. With the previous model numbers only the digits before the dash (14c26s) are needed for part lookup.

White-Rodgers parts are identified by a part number or manufacturing code. Often the manufacturing code changes but the part number remains the same. Such would be the case if White-Rodgers made improvements to the part, but the part remained fully interchangeable with the previous version.

White-Rodgers part numbers start with the letter F, such as F811-0398. The manufacturing code starts EAC A, example EAC A811-0395. Sometimes the EAC is omitted and the code starts with just the A. The manufacturing code is often stamped in black ink. If using a manufacturing code. lookup the part number in the A to F Cross Ref, then search our site for the part number.

Power Supply Compatatibility

The current replacement power supply (F858-0475) replaces most previous 120v supplies. This power supply only needs to be connected to 120v and will output 6450 vdc.

This supply will not replace supplies denoted as dual voltage in the cross reference. Dual voltage supplies where used with cells that required two voltages, one for the ionizing wires, and a lower voltage for the collector plates. These supplies are no longer available and such models need to be replaced.

The F858-0475 replaces these previous part numbers:

• F858-0475 Installation
• F858-1002 Installation

Simple Power Supply Test Procedure

Troubleshoot Problem:

• The neon indicator light is not coming on
  
• The cells never spark
  
• Power box switch is ON
  
• Door is tight in place
  
• Blower is ON

1. Verify Power is Present.
   Unplug the power box cord and operate a drop-light in the 3-prong receptacle verifying an acceptable voltage and current.


2. Check for Shorted Cells
   A shorted cell can prevent the indicator light from coming on. Remove both cells, with door back in place operate without cells. If the unit now appears OK with indicator light ON, then the cells have a problem.
   
   
   1. Operate without cells
   2. Check cells for broken wires
   3. Check cells for bent plates
   4. Check with one cell at a time (align cell with contacts)


3. Replace or Repair Power Box.
   If the power box is plugged in to 120v and the LED indicator still does not light without the cells (blower must be running), then the problem is in the power box.

• Check the on/off switch, 3-Prong Connectors, and wiring.
• Bypass the Air Flow Sensor (AFS), The AFS is a switch that closes when air flow is present. By-Passing the AFS will force on the power supply, See AFS By-Pass section below.
• An LED problem is not likely if the cells never spark. The LED will not light if its blue and white wires are crossed.
