Major malfunctions

Noise and whistling

Noisy equipment due to lack of coolant or scale. Refill with water so the appliance doesn’t overheat and stop making noise. If antifreeze boils and you hear a characteristic whistling sound, it seems that layers of scale have separated. The way out is to flush the heat exchanger and fill the cavities with a special solution.

Also look at the pressure gauge: if the pressure is low, the injectors whistle at ignition. You need to bleed the air.


Smoke after ignition is due to a lack of air. If there is not enough air in the gas/air mixture, the gas does not have time to burn and smoke. To fix the problem, you need to adjust the air sucked in by the burner. The technician will diagnose and repair the unit.

It does not turn on

If the boiler does not work, the probable causes are as follows:

  • The burner is clogged.
  • The valve is not open.
  • Lack of gas pressure in the chamber.
  • The ignition is broken.
  • Lack of voltage.
  • In open boilers there are problems with drought.

And now briefly about fixing the situation. Installing an uninterruptible power supply will fix unstable voltage. If the varistor exploded because of the difference, it should be re-soldered. It makes sense to check that the zero and phase connections are correct, and then that the sensor circuit in the room and boiler thermostat is intact.

Note that ice or other objects in the chimney prevent the escape of carbon monoxide, which is why the automatics does not allow the device to turn on: melt the icing and everything will come back to normal. If there is not enough draft, you need to reduce the height of the chimney (and vice versa) or clean the chimney. For San Marcos Heating Repair, contact a service center.


Condensation on the combustion product discharge pipe is fraught with corrosion of the heat transfer chamber (a very expensive boiler part), and the liquid can get into the electronics area and ruin it. Heating Repair in San Marcos, CA is simple and more complicated:

  • Open the air intake hole in the top wall near the chimney vent.
  • Redesign the chimney with the right material and replace it with a new one.
