What are the two primary reasons that BJ thermostats start to leak gas around the knob?

The two primary reasons that BJ thermostats start to leak gas around the knob are typically related to the physical integrity and proper closure of the appliance components. When oven doors do not shut tightly, this can create a breach that allows gas to escape, leading to a leak around the thermostatic controls. Similarly, bowed front panels can cause misalignment, preventing proper sealing of the thermostat housing, also contributing to gas leakage.

In the context of gas appliances, ensuring that all components are correctly aligned and sealed is crucial for safe operation. The physical wear and environmental factors can lead to these physical changes in the structure of the appliance, making it essential to regularly check the integrity of these parts. Recognizing that these issues can cause gas leaks highlights the importance of preventative maintenance and regular inspections to ensure the safe and efficient performance of cooking equipment.
