Service Information

 The following is service information for the PP203Safety Flameout Control:3. Safety Control / Photocell 

First we must understand the PP203 Flameout Safety Control works directly with the heaters photocell circuit.
In the past, it has been the single most misdiagnosed part of the heater. It is suggested that all controls be checked per instructions listed in the Troubleshooting Section, prior to replacement.

The PP203 safety flameoutcontrol circuit consists of a photocell (light sensitive cell) and a safety control. The photocell is used to sense the presence of light inside the combustion chamber.
The photocell varies its electrical resistance in relation to the light rays which contact its surface. When the heater is operating properly, the photocell sees sufficient and proper color light, which keeps its resistance low.
When the photocell does not sense the proper color or amount of light, the resistance of the photocell increases and forces an electrical current to flow through the solid state trigger circuit.
The current flows into the circuit breaker and heats a metal bar causing the bar to warp (bimetal). The warpage releases the spring loaded reset button, which breaks all power to the heater. As a service technician, it is important to understand the operation of the safety control.


Check That Reset Button on Safety Control is Fully Depressed

Visually inspect the black reset button on safety control. The button must be fully depressed and latched in for operation.

Check Wiring Connections at Safety Control and Wire Nuts for Proper Fit.

Wire Nuts
Physically check electrical connections at wire nuts and safety control for proper fit.
Check for continuity between male prongs of power cord to safety control and make sure all connections are secure.

Testing the Safety Flameout Control

With the heater disconnected from AC source, disconnect the red and black wires connected to the safety control. Push reset button in.
With the ohmmeter on the 0 to 200 OHM scale, check for continuity across terminals where wires were removed. Meter should indicate 0. If a high resistance is detected here then you will need to replace the device.
If your reading is 0 then the circuit breaker inside of the safety control device is working properly and the photocell side of the safety control device will need to be tested.

Make sure unit is disconnected from AC source.
With an 12 inch jumper wire we need to remove the Photocell from the safety control circuit for testing purposes only, do not run the heater without the photocell in series for more than 15 minutes.
Remove the Photocell from the series and connect one end of the jumper wire to where the white wire was connected and the other end of the jumper wire to where the blue wire was connected.
Now plug the heater in and test, if the safety control circuit breaker still trips then you will need to replace the safety control device with a new PP203 Flameout Safety Control Device.
