Service Information
Many times we see the 231844 and 231959 Glo-Bar replaced with an after market Glow Bar and then the heater will not ignite.

Many times the installer will order and install a new module board for the heaters and the wall furnace will still not ignite even though the Glow Bars does glow and prepare to ignite.

This is due many times to the wrong glow bar being used as a replacement part.

The 520899 Control Board needs the specific ohms that are passed through the 231844 and 231959 Glow bar and will not sense that the correct ohms are being sent to the board with most after markets glow bars.
