16. Troubleshooting

17. Troubleshooting of the R7184U
The indicator light on the control provides lockout, recycle and cad cell indications as follows:
Flashing at 1 Hz (1/2 second on, 1/2 second off): system is locked out or in restricted mode.
Flashing at 1/4 Hz (2 seconds on, 2 seconds off): control is in recycle mode.
On: cad cell is sensing flame.
Off: cad cell is not sensing flame.
Cad Cell Resistance Check
For proper operation it is important that the cad cell resistance is below 1600 ohms. During a normal call for heat, once the control has entered the Run mode, press and release the reset button. Indicator light will flash 1 to 4 flashes. See next slide for equivalent cad cell resistance.

18. Troubleshooting: Diagnostics
Push lockout button once to get cad cell resistance and system status
