Replacing a faulty thermocouple is a common and relatively simple repair that ensures the proper functioning of the gas appliance.

How the Thermocouple Works

A thermocouple is a sensor used in gas appliances to detect the presence of a pilot flame. Comprising two different metals joined at one end, it generates a small electrical voltage when heated. This voltage signals the gas valve to remain open, allowing gas to flow to the pilot light. Suppose the pilot light goes out or the flame is too weak. In that case, the thermocouple cools, generating less voltage and prompting the gas valve to close, preventing gas leaks.

Damaged Chimney Liner

A damaged chimney liner can compromise the safety and efficiency of a fireplace or heating appliance. The liner protects the chimney walls from heat and corrosion while promoting proper ventilation. Cracks or deterioration in the liner can lead to fire hazards and allow harmful gases to enter the living space. Regular chimney inspections and repairs are essential to address liner issues promptly.

Dirty Filters

Dirty or clogged filters in HVAC systems can impede airflow, reducing the system’s efficiency and increasing energy consumption. Additionally, dirty filters can lead to poor indoor air quality as they fail to capture dust, allergens, and contaminants effectively. Regular filter replacement or cleaning is a simple yet crucial maintenance task to ensure optimal performance and air quality.

Exhaust Fan Issue

The exhaust fan plays a crucial role in ventilation, especially in kitchens and bathrooms. Malfunctions, such as a noisy fan, slow operation, or complete failure, can lead to poor air circulation, moisture buildup, and potential mold growth.
