Thank you for your question regarding the Rheem SP20296 Gas Control Service Kit.

While we cannot provide diagnostic services, we highly recommend that any troubleshooting or servicing be performed by a licensed technician familiar with gas water heater systems and local safety codes.

That said, in general terms, if your water heater's blue indicator light is blinking continuously but the burner is not igniting—even when the gas valve is set to a high temperature—this could suggest one of several potential issues:

• Thermopile or Flame Sensor Issue: The thermopile may not be generating enough voltage to signal the gas control valve to open. A dirty or faulty sensor could prevent ignition.

• Gas Control Valve Malfunction: The valve may be failing to open despite being set to a high temperature.

• Igniter or Pilot Light Problem: The pilot may not be lighting or staying lit, preventing the main burner from igniting.

• Error Code Indication: The blinking blue light could be an error code. Count the blinks—this usually corresponds to a diagnostic code printed on the unit label or in the service manual.

A licensed professional familiar with your specific application will be able to determine if one of the above—or another issue—is the root cause. We strongly encourage having a qualified technician inspect the unit to safely diagnose and resolve the issue.
