Ignoring unusual sounds can lead to more significant problems down the line, so it’s crucial to have a qualified gas heater repairs Newcastle technician inspect and repair your gas heater promptly.

Unpleasant Odors

In such cases, turn off the heater, ventilate the area, and contact a gas fitter immediately to inspect and repair the leak.

Yellow Or Flickering Flame

A healthy gas heater flame should be blue with a consistent, steady burn. If you notice that the flame is yellow or flickering, it may indicate a combustion issue.

Soot buildup can obstruct airflow and create a fire hazard. Regular cleaning and maintenance by a professional can prevent this issue and ensure safe operation.

Pilot Light Problems

The pilot light is a crucial component of your gas heater’s ignition system. If the pilot light frequently goes out or struggles to stay lit, it’s a sign of a malfunction. Common causes of pilot light issues include dirty or damaged thermocouples, gas supply problems, or ventilation issues.

Uneven Heating

If you notice uneven heating in different areas of your home, it may indicate problems with your gas heater’s distribution system.
