What to Do Next

Step-by-Step Action Plan

Follow these steps before calling a technician — you may be able to resolve the issue yourself.

Check the Thermostat

Start by ensuring the thermostat is set to the desired temperature. If it’s lower than expected, adjust it and wait to see if the boiler responds.

Inspect the Pilot Light

If your boiler has a pilot light, check to see if it is lit. If not, follow the manufacturer’s instructions to safely relight it.

Examine for Leaks

Look for any visible leaks around the boiler. Tighten connections and check for signs of corrosion.

Bleed the Radiators

Use a radiator key to bleed air from your radiators. This can alleviate noises and improve heating efficiency.

Check Water Pressure

Verify the water pressure on the gauge. If it’s below the recommended level, follow the manufacturer’s instructions to repressurize.

Pro Tip

Always turn off power to the unit at the breaker before inspecting any components. Safety first — even for simple checks.
