How to Check the Boiler Burner for Repair?
Knowing the things that you can do to fix problems regarding burner for boiler will help you in troubleshooting the technical issues of your combi boiler. Here are the steps that you can do to check your boiler burner for repair.
1. If your combi boiler has a standing pilot light, you should check to make sure it is lit. Through this, you can assure yourself that the burner boiler is working. The first step is to check the thermostat. You have to ensure that it is set above the actual room temperature. Afterwards, you should go to the boiler and see if the circulator boiler pump is running. You should feel the motor with your hand to see if it is hot. If the pump is not running and it is cool, check the breaker that supplies power to the boiler burners.
2. If the motor feels very hot, the problem could be the run capacitor, the motor, or the pump itself could be locked up. If the burner boiler is cool and the breaker is on, the problem could be the thermostat or the circulator relay. If the circulator is running, you need to continue your boiler burner troubleshooting by checking the temperature.
3. You just have to press gauge on the boiler. If the temperature and pressure is normal, there is probably air in the system. This is common on systems with the old style of manual air eliminators. You can resolve problems like this with your boiler burner by easily replacing the old manual type with modern, automatic, float type air eliminators.
4. If the combi boiler pressure and temperature are abnormally low, you have to check it to see if the vent damper is open or the inducer fan is running. If not, you need to shut off the breaker to the unit. Then, wait a couple of minutes and then turn it back on. If the damper does not open or the inducer doesn’t start, the problem could be the boiler control or the aqua stat.
