Too much gas build up is why it locks out for a period of time. This watchdog lockout allows for the gas to dissipate. This time delay ensures excess gas does not become a hazard and cause an explosion.
Another cause of burner lockout is from contaminated oil.

Air conditioner compressors usually fail due to one of two conditions: time and hours of operation (wear out), or abuse. There are some failures that can occur elsewhere in the system that will cause a compressor failure, but these are less common unless the system has been substantially abused. Ignition Control System 1. Thermostat calls for heat 2. Ignition controller requests a spark to the electrode which ignites the gas 3. Control uses flame rectification or sensor to identify if flame is present 4. Ignition controller sends signal to open gas valve 5. When thermostat is satisfied, gas valve closes to shut off main burner gas 28

• Furnace lockout due to an excessive number of ignition “retries” (3 total)1. • Failure to establish flame. Cause may be no gas to burners, front cover pressure switch stuck open, bad igniter or igniter alignment, improper orifices, or coated/oxidized or improperly connected flame sensor. • Loss of flame after establish- ment. Here’s how you can fix a stuck gas furnace pressure switch. Step 1 – Inspect the Control Board. The first step is to examine the control board and check if the switch is stuck due to an obstacle in its path. The switch is connected to hoses and the water in these can sometimes cause a little bit of a problem.
