After trying but in vain, you have just noticed that the malfunction seems to come from the boiler which no longer wants to turn. Why is your boiler not starting? In this guide article we will explain everything you need to know about your boiler which breaks down.
What exactly causes a thermostat fault?
Now, if you notice that you cannot control your boiler from the thermostat, you need to know that one of the two components is no longer working.
To properly decode where the problem is coming from and how to fix it, you will first need to find out who is having the problems. To get started you need to clear out some of the basics that could be causing your heating problems you can even call Emergency plumber Paris
In order to achieve and maintain the optimal operating temperature of the engine, the thermostats play the role of a monitor of the engine cooling system while controlling in particular the cooling temperature on the one hand, and regulates in a determined manner its flow into the radiator on the other hand.
The famous and best known cause of a permanently open thermostat is a blocked piston. Abrasion can cause damage to the thermostat but also a defect. The open thermostat can also be blocked due to a foreign body. Therefore it cannot close when it cools.
Once the thermostat spring plate is very well supported the thermostat housing but also by the thermostat itself at any time can come loose this explains why the thermostat is no longer suspended
More and more and with time the seal of the expansion element begins to leak allowing the wax to escape. And this is what shows depending on the material of expansion the element of the latter no longer has enough force to function well automatically and that the thermostat remains closed.
On the other hand, the best known cause of card-controlled thermostats is an electric actuator that no longer works. So the movement of the working piston over time gives way to cooling water in the actuator and blocks it.
Your margin of maneuver in the event of a breakdown
The thermostat is therefore a little electronic marvel. Its programmer is completely electronic. To stop or start the boiler, its regulator uses a bimetallic thermal switch. It is out of the question that you can intervene on the programmer. As for the operation of the bimetallic strip, it is far from being within the reach of a plumber.
Broken boiler
If you’ve followed these basics and you still can’t find an answer and your thermostat and boiler aren’t communicating as they should. This means that the malfunction of your boiler is still there. This can be explained for several reasons.
Indeed, if your boiler is having trouble responding to your thermostat and is no longer able to operate normally, unfortunately, now is the time to say goodbye to your old boiler.
In summary, if the thermostat no longer opens, you should only continue driving if you cannot stop. You should always monitor the temperature. With an open thermostat, continuing your trip is not a problem but you pollute more.
