Why does my boiler keep blowing a fuse?
Does your boiler keep blowing new fuses? If it does, there’s probably a faulty component on your heating system that’s short circuiting. The most common are either the pump, the boiler’s fan, or a mechanical timer clock. With some testing, a good heating engineer should be able to isolate the cause of the problem.
Do boilers have internal fuses?
Sometimes boilers will have multiple internal fuses. These are usually fuse spurs – a small socket, with a red window. A Gas Safe Engineer will be able to check the fuse spur, replace it if necessary, re-test your system to ensure nothing underlying causes the fuses to blow again.
Where is the reset button on a combi boiler?
Your boiler restart button, also referred to as ‘lock out’, is located on your boiler burner unit. Usually, the burner unit front door cover will need to be removed to gain access to the control box reset (when ‘tripped’ the button is normally illuminated).
Can a condensing fan be fixed to run continuously?
You should also be given a copy of the operating instructions for the boiler. I would be very surprised if the fan was meant to run continuously on a condensing boiler, unless it has a pilot light. It sounds as if an incompetent person may have fixed the fan to run continuously to override a safety device.
Can a boiler fan fault be an air fault?
The fault code system on boilers isn’t particularly complex. Air faults can often be confused with fan faults, and vice-versa. So, before writing the fan off it’s worth considering the following problems. A blockage in the flue means harmful gases can’t escape.
What should I do if my boiler fan is running continuously?
The LGS Check has to be carried out annually by a Corgi registered gas installer. You should also be given a copy of the operating instructions for the boiler. I would be very surprised if the fan was meant to run continuously on a condensing boiler, unless it has a pilot light.
Can a fan be re aligned on a boiler?
Re alignment may be possible, however, it may also be loose and beyond repair. The fan speed control resistor is able to withstand larger currents so as to generate heat. The resistors are enclosed within a metal casing with a heat sink connected to it, which then connects to the boiler chassis to dissipate the heat quickly.
What happens when the fan on a boiler stops working?
When it recognises this issue, it effectively tells the PCB that the fan isn’t working. And, just as a boiler won’t fire up without the fan working, if at any point the PCB receives the signal that the fan has stopped working during operation, it’s going to cut gas supply to the gas valve.

Why does my Furnace Fan not shut down?
If the furnace tries to start but cannot keep running then there is a different problem such as no fuel or an unsafe condition. On 2020-03-04 by (mod) – blower motor on air conditioner will not shut down. Have you checked for shorted wires anywhere in the control circuit? blower motor on air conditioner will not shut down.
What to do if your a / C fan won’t stop running?
1. At the room thermostat: the FAN-AUTO-OFF or FAN ON/OFF switch on the room thermostat should be checked. The fan control should be set to AUTO. You can try turning the switch to OFF too. Other snafus such as a shorted thermostat wire can also cause the A/C or warm air furnace fan to run continuously.
