You surely don’t want to return to the caveman period, where people had to rely on coal and wood fires to heat their sweet abode. And, when you notice that your boiler’s timer is not working, you feel like it’s that period again. Nothing can be as disastrous as returning to your home and finding out that it is practically freezing.
People quickly blame the central heating system when they notice no heat. Many a time, it is the boiler’s timer that demands repair. These clocks indeed tend to rust and age after a couple of years. More importantly, you must diagnose the issue with your boiler’s timer at the earliest.
In this post, we’ll find the reasons why your boiler’s timer or mechanical is not working. Not only that, but you’ll also see some handy ways to fix that boiler time. Let’s get to the crux of the matter before you entirely freeze up!
Boiler Timer Normal Operation
Before we discuss the potential causes, it is essential to find how your boiler timer works. It will help you identify and fix the central heating system more efficiently and quickly. Typically, when you turn on the hot water tap, the boiling water should instantly start flowing.
Some homes require more hot water during certain days than others. A good-quality boiler will be flexible so that it can fulfill these demands. For instance, one family member takes a bath with hot water early morning, whereas the other members like bathing at night.
You can ensure that the tap does not run out of hot water by making specific changes to your boiler’s controls. The right hot water boiler will save energy, time, and frustration.
The good thing is that most boilers are economical in terms of controlling the heating system. Are you outdoor all day for work? In that case, setting your boiler time can save you some cash. The only downside to using this timer clock is that it does not ensure heating on weekends.
Is your boiler not working? There could be several reasons behind that, such as:
- Broken ignition leads
- A fault with the boiler PCB
- Faulty thermostat
The Common Boiler Timer Faults
There are myriad reasons why the boiler’s timer controls are not working. The good news is that most of these problems are easily fixable. In this section, we’ll briefly highlight the common reason why that boiler timer has been misbehaving.
Timers are an attribute that was more common in old boiler models. The new boiler models may or may not have this feature. Most of the homeowners install a room thermostat all by themselves to ensure convenient heating.
If something is causing the thermostat to operate incorrectly, it can send the boiler’s wrong signals. As a result, the boiler will keep turning on and off. So, if you have a thermostat guiding the new boiler, you know what to do.
The most common reason behind the timer not working is because your location is practicing daylight savings. Before you directly blame your new boiler, take note of your daylight saving months. It may also happen that your boiler timer is not functioning because of a power outage. In any case, you should figure out the core reason behind the issue before jumping to fix it.
Fixing A Broken Boiler Timer
Finally, an essential part that has got you glued to this piece. It’s time to fix that broken boiler timer so that your central heating system is up and running again. We’ve divided this section into several parts based on the different issues. Let’s get reading!
Central Heating Time Settings
Many boilers still use an old mechanical clock. If this is the case with your boiler, you should understand when the radiators turn on and off by themselves. A power outage is another common reason why your boiler is not working.
Sometimes, the power can go off whenever you are not at home. You can determine this situation by looking at the other clocks in your house. Power cut can cause the boiler timers to reset. Because of interruptions in the boiler’s electrical supply, it might not fire up when needed.
The seasonal clock change can also cause your combi boiler not to work. Additionally, the situation also might be due to damage to mechanical controls.
The only solution here is to keep an eye on the timer settings. The timer clock of your boiler is prone to confusion owing to various reasons.
Recent electric work, electricity supply cuts, and seasonal changes can be the reason behind the faulty timer. Any of the mentioned reasons can result in your boiler completely shutting off.
You must check if the central heating time settings are correctly set or not. Often, the day and nights get mixed, and your boiler timer will be working in the opposite direction. In case you are having issues with the timer controls, the best thing to do is hit the reset button.
The above solution didn’t work? Maybe it’s time to check the power supply. You can start your fixing process by checking if the boiler is receiving power or not. Is the boiler turned on? Is the boiler heating? Besides, some models possess different switches for radiators and hot water.
If your boiler model has different switches, then you must move to the fused spur. On the frontal plate, you can find the blown-up electrical fuse. Usually, this fuse is not hard to locate, as it already comes with a sign. To fix this issue, remove the cover and replace the fuse with a new and correct size one.
The dodgy wiring can also prevent your boiler from properly functioning. It is better to get a gas safe engineer or call a professional to check out this issue.
Note: Always make sure to check if the electric supply is off before reaching the fuse.
The sensors inside the thermostat device allow it to analyze the temperature of the area. The air around this tiny device triggers the heating in the boiler to shut on and off. If the room temperature is cold, it will automatically turn itself on, and vice versa.
Another reason behind the thermostat malfunctioning is dying batteries. There can also be a fault with your thermostat due to the build-up of dirt and debris.
The solution to the fault in the thermostat is to replace the dead batteries. Remember to wear gloves while removing the batteries. You may also be required to clean the thermostat. Check the dirt sites in the thermostats, and remove them effectively with cotton buds or a soft brush.
You must also take a look at the location of the thermostat. The thermostat might not be working because there are heating sources near it. Make sure that the thermostat is away from kitchen appliances and direct sunlight.
Heating & Hot Water Settings
This issue here is pretty obvious, yet one of the significant reasons your boiler timer is not working. Make sure that you have shut off the heating instead of turning off the hot water.
Even if you haven’t, someone else in the house might have done it by mistake. In this case, you don’t need to do anything but only switch the hot water back.
If you have a new boiler, you might notice that it has a mechanical timer. The old but gold way to fix boiler clock problems is by resetting the controls. Remember that these boilers may revert to 12-midnight. You have to use the manual to set and change the time correctly. The boil timers can get a too complicated affair if you ditch the user manual.
Brand Specific Boiler Timer
Boiler controls may indeed differ from one brand to another. Especially if you’ve bought a new boiler home, it may give you a tough time to turn itself on. If you have a new boiler from a different brand, it is better to resort to the user manual.
The user manual is the right place to understand the problem in your boiler or boiler timers. Though the suggestions mentioned earlier are common boiler fixes, you can also take an engineer’s help. For further information about a brand-specific boiler clock, you can refer to the table below.
What to Do If Your Boiler Timer Still Isn’t Working
If none of the above solutions are working, it is better to call up a gas safe engineer to check and fix the problem with the programmer. It is better to call a professional to come and visit your broken boiler. These professionals will have time-tested solutions to make your boiler start working and heating again.
You may need to call for professional help if you see a completely broken thermostat that can’t detect the temperature. The gas safe professionals thoroughly check the boiler heating system. They will correctly identify the core of the problem in the radiator or the boiler.
No matter what brand, the plumbers will set your boiler heating mechanism in no time! If your professional cannot repair the boiler still, maybe it is time to get a new one.
