Boiler troubleshooting instructions

If your boiler is malfunctioning, follow these steps. By doing so, you may be able to restore its functionality and avoid the need for a service call to repair your boiler.

Check your tank gauge levels: To ensure optimal heating in your home, it is crucial to maintain an ample supply of heating oil or propane for your boiler. If your tank falls below 25% capacity, please contact us immediately for an emergency delivery. By the way, you can prevent fuel shortages by enrolling in our Automatic Delivery service! We utilize your fuel consumption history and advanced software to accurately anticipate your fuel requirements and schedule deliveries proactively, ensuring you never run low.

Inspect the thermostat: Ensure that your thermostat is set to a minimum of five degrees higher than the current temperature in your home. Additionally, make sure that the thermostat is switched to “heat” mode (as it is a common issue during the early stages of the heating season). Finally, remember to inspect the batteries and replace them if necessary. If this doesn’t work, move on to the next step.

Check the boiler: For steam boiler owners, it is important to regularly monitor the water level in the gauge glass. Ensure that it is at least half-full. If it falls below this level, please do not hesitate to contact us. If the water level is satisfactory, you may proceed to the next step. Please note that this instruction is not applicable to hot water boilers, so you may skip this step if you have one.

Push the reset button ONLY ONCE: Locate the “RESET” button. Before pressing it, make sure to adjust your thermostat to a temperature that is at least five degrees higher than the current temperature in your home. Once you’ve made the adjustment, proceed to press the reset button. It’s important to note that you should only attempt this step once. Assuming you have sufficient fuel, pressing the reset button should resolve the issue. However, if it fails to do so, refrain from making multiple attempts as doing so can potentially cause further damage to your boiler. In the event that the reset button doesn’t work, it indicates that your boiler requires professional attention. Contact P. Gagnon & Son promptly for expert emergency no-heat service.

Check the breaker box: In the event that an excessive amount of electricity has flowed through the circuit responsible for controlling your boiler, it may cause the breaker to trip. By simply flipping the circuit breaker switch, you can restore power to your boiler. Please proceed to perform this action and verify if your boiler is functioning as intended. If the issue persists, kindly reach out to us for further assistance.

If you haven’t gotten your boiler its annual maintenance tune-up, it’s not too late! Contact P. Gagnon today to schedule it and enroll in a service plan.
