Honeywell F50F Series 20x25 Parts

Where is my F50F Model Number

Order parts based on your model number. The F50 model number is located on the inside of the door.

Otherwise order parts based on the overall size of your cells. The F50F came in 5 sizes. The smallest model has on cell 121/2x20. The two cell models are 16"x20", 16"x25", 20"x20", 20"x25".

If your air cleaner was manufactured by a diferent company and looks like ouu photos, then it is a honeywell air cleaner. Honeywell also had an earlier F50E that was similiar. The most noticable difference between the F50F and the earlier F50E is the size of the powerbox. The F50F power box runs the full lenght from front to back. The F50E power box is half the lenght.

The F300 is identical to the F50F but with different paint color.

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 Neon indicator still does not light without the cells, then the problem is in the power box.

1. Check the on/off switch, interlock door switch and wiring.
2. Bypass the Air Flow Switch (AFS), The AFS is a sensor that signals the power supply when air flow is present. Disabling the AFS will simulate the ON state. Using a jumper wire, ground AFS resistor to the chassis, see AFS Tech Notes.
   • Replace Air Flow Switch, if the Neon indicator lights and unit appears to work with the AFS disabled.
   • Replace Power Supply, if the Neon indicator does not light with the AFS disabled and no cells to short the output.
   • Neon problem, is not likely if test button does not spark. The neon lamp voltage should measure 125 vdc.

F50F - Determining Series One or Two

W8600F Series Two W8600E Series One	Choosing the replacement power box may be dependent on the series. If you do NOT have the optional wall mounted Remote Performance indicator (W8600F), the series does not matter. If you are replacing a power box of any series and do NOT have W8600, we recommend choosing the Series 2 Power box. F50F Series 1 was manufactured from 94 to 97. The series 2 was manufactured from 98 throught 06. The Series 1 power box comes with a 4 connector would be used for the optional W8600E. The Series 2 power box has a knock-out for a terminal strip. The terminal strip would be included with the optional W8600F. The F50F Series 2 power box is the same used in the current F300.
