Baseboard Heater Won’t Turn off – How to Fix

Heaters are those mechanical components for our house that saves us from being cold in the winter season. Yes, we can always use an extra layer of clothing. But you can realise how hard it can be to move around the house with those additional layers. 

But the temperature may not stay the same. There could be days when you may not need to keep the heater turn on the whole day. There where the problem begins. It is not turning off, and you do not need that much heat right now. The fact is, you are not alone that face this problem. Everyday many surveys record this type of complaint. 

The steps to solve continuous or unwanted heating are not very difficult. Most of the time, troubleshooting solves the problem. But sometimes there can be severe types of situations. Whichever it is, in this article, we are going to describe a few steps through which you can fix the problem of your Baseboard Heater’s “Not Turning Off” situation. 

Often the thermostat is a single pole. If the heater element’s end is electrically nearer, the thermostat should become ground-faulted; the non-switched pole’s power can continuously supply 120 volts to the heater element. That would be the first thing you should test. There can be many problems like this. We will help you to identify them in this article;

Fixing A Baseboard Heater Won’t Turn off

Baseboard Heater Won't Turn off - How to Fix

Most of the time Baseboard Heater is used for those homes, which do not have a centralised heating system. An electric baseboard heater faces a lot of complaints. It could be anything like carbon buildup between its thermostat’s contacts or loose electrical connection in the circuit-breaker panel, causing the system failure. 

Let’s not waste anymore of your precious time describing the problems here. Let’s get started with the steps to fix your heater.

  • Is it still on?

As we already understand, heaters take the time they prefer to heat up. Likely, they will still heat up for a few minutes after shutting it down. The sure way to say is to pop the service covers and test with hopefully non-contact testers, hopefully, a clamp-on ammeter. But at some point, you’re going to want to try the actual voltage. 

One way to calculate is the electrical meter of your home. Since it has a rotating disk or equivalent optical readout, which indicates the rate of power usage. Switch off all other big loads to measure the heater.

  • Tripped Heater’s Circuit Breaker

If a circuit breaker trip involves a short section of an electrical circuit, this sort of problem typically leaves some visual signs. Such as a burned wire terminal. Switch the circuit breaker into the “Off” position. Never depend on the tripped location as a disconnect for safety reasons. Open the electrical compartments of the baseboard heater, and check each component and its wire connections. Follow the wire between the power supply panel and the thermostat, searching for some sort of damage.

Disconnect the thermostat load conductor from the baseboard heater. Turn the thermostat to the hottest spot. Test the thermostat for consistency between the load line and the ground. If the system uses a wall-mounted thermostat, test the wire between the thermostat and the baseboard heater.

 If the meter shows any continuity, replace the thermostat.

  • Dust Build Up
Faulty Thermostat

It can be effortless to restore an electric heater, as long as you can get the product’s replacement parts for it. In certain instances, it is not a replacement component that is required, but rather some routine servicing. Over time, various problems will happen to our electrical equipment, and the most common concern is loading up the dust within the appliance. This dust can cause all sorts of issues, as well as seeing smoke or smelling odd smells.

We use a thermostat to control the temperature of our house digitally. We have to set a temperature under which the heater will turn on and beyond which the heater will turn off. But if your thermostat is not measuring the temperature appropriately, you can not expect your heater will turn off when it needs to be. 

In this case, you might have to troubleshoot the thermostat

  • Damaged Temperature Coil

If your heater does not turn off until it reaches a predetermined heat stage, it is possible that your temperature sensor should have been burned out, and you need to replace it. You would need to arrange the exact coordinates to restore this electrical heater section, remove the old one from the unit and repair it. Generally, the coils are screwed in position on the device’s interior away from the heater coils and can be disconnected quickly. Again, consult with the manufacturer of the machine to see which components can be ordered and replaced.

  • Faulty Temperature Sensor 

Baseboard Heater comes with a built in the sensor in it. If you have been using the baseboard for a long time, the sensor can get malfunctioned. Of course, it can also happen with new heaters. If your heater is not turning off when it should be, do not hesitate to tet your heater sensor. With a multimeter, you can do it by yourself. If the sensor does not have any continuity in your multimeter, take the liberty to change the sensor.

Some Important FAQs 

As we always say, you might have some confusion after any discussion about the content. Similar to that, you may have Some questions after the above elaboration. Let’s have a question and answer session to solve this confusion;

  • What if and why Baseboard Heater won’t turn on? 

To ensure that the heat is set at the right temperature, check the thermostat. If, after a few minutes, the heater does not emit heat, check the electrical system. Tripped breakers are typical issues with baseboard heaters. Inspect the valve inside the radiator.

  • What would be the replacing cost for a baseboard heater?

The cost of building a baseboard heater on average in Germany is $88.35 a heater, varying from 81.55 $ to 95.16. The average price of labour and resources per heater is 395,75 dollars, from 290,88 to 500,62 dollars.

  • What could be the options for replacing baseboard heaters?

You have two options to replace the baseboard heater: electric convection heaters or hydro

nic heaters. Both styles are well-matched to baseboards in any room and can be put under windows or near recessed doors. Heating belt, like a toaster, is used to heat the room with electric heaters.

  • Is my baseboard heater still working?

The circuit breaker pad, the thermostat and the heater are available in three locations. The easiest way to initiate the panel is to recognise issues. The next position is the thermostat, and the heater itself is potentially unreliable if it scans. Switch off the power of the thermostat.

  • Why do heaters stop blowing hot air?

Thermostats and filters affect these conditions the most often. Make sure the ventilation is not blocked or restricted in your furnace. If the oven just warms up nicely but blows continually, the limit switch can pose a problem even if it is not warm.


Heaters are essential components if you live in a place where the warmest day could be 10 degrees celsius. One might say, in a situation like this, why would anyone want to turn their heater off. But for many reasons, you might need to turn the heater off. One reason could be for saving electricity. Whatever your reason is, if your hater is not turning off, do not hesitate to take the necessary steps to fix it. But as we always recommend, do take the liberty to call upon an expert if you feel so.
