White-Rodgers SRP (Super Remote) Series Parts

White-Rodgers SRP Series 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 SRP model numbers were 12c11s-010. See the Model Number Cross Ref for more examples. With the previous model numbers only the digits before the dash (12c11s) 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 F811-0418. The manufacturing code starts EAC A, example EAC A811-0418. 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.

Simple Power Supply Test Procedure

Troubleshoot Problem:

  • 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
  1. Verify Power is Present.
    Unplug the power box 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 the cells. If the unit now appears OK with indicator LED ON, then the cells have a problem.
    • Operate without cells
    • Check cells for broken wires
    • Check cells for bent plates
    • 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.

Air Flow Sensor By-Pass Test

To test the power box without air flow requires by-passing the air flow sensor (AFS). The AFS is a switch that closes when air flow is present. The 120v power passes through the AFS switch and on to the power supply.

The AFS connects or disconnects the neutral side of the 120v. The 120v neutral wire passes through the AFS and then on to the power supply. The neutral wire enters the AFS on the white wire, and exits the AFS on the white/brown wire.

By-passing the AFS applies the 120v power directly to the power supply. This will cause the power supply to operate with or without air flow.

The AFS by-pass can be used to isolate a problem with the power supply or AFS. If the power supply operates with the AFS by-passed, then there is a problem with the AFS and not the power supply. The collector cells need not be connected.

Photo below shows by-passing the AFS. Disconnect the modular plug from the AFS and then connect the white wire to the white with brown stripe wire. We did this using the yellow wire shown below. We used a 14 gauge wire because if fit snug in the connector. This will force on the power supply and the green LED will light. white-rodgers SSt series Air Flow Sensor By-Pass Test

SST Power Box Bench Test

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.
