You may have to rip the sheathing to reveal more wire before striping the wire casing back. Test the voltage detector on a different and known live wire before using it to test inside of the wall heater. This test is for ensuring there is no power in the electric heater. Repeat this test on different locations within the heater. The thermal fuse is a safety device that will shut off power to the space heater if it overheats. Its purpose is similar to the high-limit safety switch.
This will allow you to determine what usually happens when the heater breaks down, spot the fault, and the right tools you need for the job. Close the ‘lockshield valve’ so you can remove your radiator from the wall. Make sure both the valve on the left and right of your radiator are open, and if you have a thermostatic valve , make sure the radiator is turned on. Also, clean the radiator from the outside as there might be a thick layer of dust that acts as an insulator, preventing regular heat exchange with the surrounding air. The solution for this problem is to install reflectors between the radiators and the outside wall so they can direct heat back into your house. A burnt smell — or a heater that’s actually smoking — is a clear sign that something is wrong.

If a higher temperature has been selected, it would not be unusual for the valves to have seized in a closed state. Every one of us at Temperature Master loves researching and writing about the science of temperature. Open the lockshield valve to allow you to dismount the radiator from the wall.

You can even buy a thermometer and measure the temperature of the incoming and outgoing radiator pipes. Then adjust the lockshield valve to get the temperature difference around 50 F . After unplugging your heater, inspect your system for dust or blockage and clean accordingly. You may also want to replace or clean your air filters for good measure.
Check Whether the Boiler Is On and Functioning Perfectly
We’ll highlight some of the most common heater problems and identify the best solutions to fix them, whether it’s repair or replacement. If this doesn’t work, then the problem could be the pump. The pump forces hot water down the flow pipe to the radiators and taps and could have become blocked with dirt or air may be trapped. Your pump should have a small nut which can be turned to release excess air. If you’re still experiencing problems, check the motorised diverter valve which controls the flow of heated water is switched on.
Power flushing is the process of removing debris and sludge that has become stuck in your central heating system over time “preventing it from functioning correctly”. The plumber attaches the flushing unit to the piping of your central heating system and pumps clean water into it. This will force any dirt, grime, rust, and debris out of your system.

On the other hand, some boilers have a “summer mode.” This gives you hot water without running the central heating circuit, which creates a possibility of a radiator not getting hot. If you see that a radiator isn’t heating up, before you get to work on it, check to see if other radiators in your house aren’t working. If all your radiators are cold, then it is a sign that there is a problem with your boiler or central heating system.
If you find that it’s broken, then you need to replace it. The fan in your portable heater allows the temperature to be regulated so that it doesn’t overheat and the high limit safety switch doesn’t turn on. The fan should be spinning without any noise but if you notice that it isn’t, your heater won’t be able to turn on until it does. A short-circuiting wire can cause your heater not to turn on. Short circuits happen when an electrical current flows outside its wire connections and finds a short circuit back to the ground. They’re usually accompanied by sparking or the smell of burning plastic and it could be to dangerous situations such as a shock or fire.

If you have a radiator heater mounted on an exterior wall of your home, then it’s possible that you may be losing some of the heat produced to the outside elements. This is particularly true if that exterior wall has poor insulation, has drafty windows/doors nearby or the radiator is recessed within the wall. It must be noted, however, that you can also find many of these same benefits in other types of heaters.
This is not uncommon for cheaper, low quality electric heaters and on a daily basis we see some of the same problems over and over again. With that being said, below we are going to take a look at some of the different reasons why your electric radiator may not be working and what you can do about it. It is recommended to turn the system off, have water cool down, and remove both lockshield and thermostatic valves. Take the radiator outside and run the clean water through the unit until all the rust, grime, limescale, and dirt are removed. You might want to use special additives to help clean the system efficiently and thoroughly.
"By unclipping the TRV you may be able to free it up, but be careful as it may be badly corroded and pop out or leak." The simple solution is to get the system serviced by a professional. Talk or chat with one of our friendly Austin, TX experts and ensure you order the right product for your needs.

This occurs because nothing prevents deposits (dirt, rust, etc. present in water and tubes) from reaching the radiator. Additionally, air can get trapped in your radiators due to installing your pump right above the supply tank, accumulation of hydrogen caused by rusting, and leaks. A good signal that this is your problem will be if the radiators upstairs are getting hot but the downstairs radiators are cold. A radiator not heating up is a fairly common problem faced by homeowners — but it is a nuisance nonetheless, particularly if it is impacting more than one radiator in your home. Usually, there is a simple explanation and putting the problem right should not be too difficult. To Joe Saratto – If you are not getting heat to your upstairs radiators, try one of two things.
Verify you do not have a valve turned off going upstairs of there are 2 separate loops. I recently moved into a home attached to a commercial building. My heat is all baseboard heaters thru out the perimeter of the home. As far as I can tell there are no separate devices to control room by room.
We often hear the question why is my heater not working, and the truth is, there are many different possibilities. Furnaces are complex systems that require a good amount of maintenance. There are a lot of moving parts and pieces that could be contributing to the system not working properly.
If it is, check the switch itself to determine whether or not it is working correctly. You can do this by connecting a different power device to the switch and then finding out whether or not it works. If the device does not turn on, the issue is most likely with the switch, and this is what needs to be repaired or replaced. When a heater gets too hot, this feature can turn the device off for safety reasons.
