For the boiler troubleshooting, We assume that boiler installed by code with a good performance of years.
First, we do a Call for heat!Boiler does not start upCheck the thermostat, if it is a battery operated, double check whether the battery is full or not.
Add water to the boiler and check the reasons why the water level is low.Faulty LWC needs to be replaced.Furnace Installation CalgaryVent Motor does not startMeasure the voltage to the vent motor, whether you get 120V or not.
Give a power of 120 volt externally to see weather the vent motor start or not, if it is starting, great.
Measure the air pressure of the pressure switch if it does not match the pressure on the pressure switch, then replace it.Check the igniter, if igniter turns on or not, if not, check if the igniter receives 120 volts.
A lot of times they are not working properly, manually open it and let the air out.If there are radiators or baseboards, check the air vents over there and let the air out.If the air couldn’t be out with the help of the air vents, it needs to be drained.Draining the boiler is a procedure.
