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.

Your problem is:
   The LED indicator light is not coming on
   The cells never spark
   Power box switch is ON
   Door is tight in place
   Blower is ON

Verify Power is Present.
Unplug the power box and operate a drop-light in the 3-prong receptacle verifying an acceptable voltage and current.
Check for Shorted Cell
A shorted cell can prevent the indicator light from coming on. Disconnect the cell, and power up with air flow. If the unit now appears OK with indicator LED ON, then the cell have a problem.
1. Operate without the cell
2. Check cells for broken wires
3. Check cell for bent plates
4. Operate with the high voltage wire disconnected at the power suppy
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.
1. Check the on/off switch and wiring.
2. If the SRP has the optional Air Flow Sensor (AFS), Then bypass the AFS, this will force on the power supply, See AFS By-Pass section below.
3. An LED problem is not likely if the cells never spark. The LED will not light if its blue and white wires are crossed.

When there is no air flow and the SST is turned on, it is normal operation for the green LED to come on for 10 seconds and then turn off. If this behavior exists with the blower running, then inspect the thermister orifice for a clog.

The AFS uses a thermister to sense air flow, see photo. The thermister heats up to 120 degrees and when cooled with air flow, the circuitry switches the power on. The vacuum in the duct draws air through the orifice and cools the thermister.

To bench test the power box, we use the setup shown below. Our fan draws a vacuum near the AFS orifice and we move the fan away until the green LED goes out. We compare this sensitivity to our test unit.

The most simple test is to just blow at the orifice with a straw. Use a mirror (shiny galvanized sheet metal) to watch the LED on the other side of the power box. The LED will turn on as soon as you blow, and go off with in a second after stopping. A hair dryer would also work.

A thermister is a device that changes resistance with temperature change.

Beware of electrical shock. The contact
and rivets are live at 6200 volts.

The White-Rodgers warranty for all electronic air cleaner replacement parts is One year. Our customers simply ship us the defective part. We test and confirm the part is defective. We then ship back a brand new part at no charge.
