Why Delonghi Ceramic Heater Keeps Turning Off?
In this section, we will discuss why your Delonghi ceramic heater won’t turn on and provide the solution to turn it on.
1. You May Forget to Plug The Heater in
You can’t turn on any electric appliances if you don’t connect to electricity. And when it comes to turning on your Delonghi space heater, you need to plug the cord into an outlet. If you don’t plug the heater into a standard outlet, the heater will not receive any power- let alone turn it on.
Ensure you plug the electric cord into a standard electric outlet. And now, press the on/off button to turn on your heater. Also, make sure the electric outlet you used to plug in a heater doesn’t get tripped.
2. You May Set the Thermostat to the Lowest Setting
The space heater won’t turn on if you set the thermostat to the lowest setting. Therefore, you will fail to turn on your ceramic heater if the temperature of your room reaches the set temperature.
Setting the thermostat to the maximum setting will be an easy fix for this issue. Alternatively, increase the temperature by pressing the + button on your remote control if the room temperature reaches the set temperature.
3. A Tripped ALCI Plug
If your Delonghi space heater is equipped with an ALCI plug, ensure it doesn’t get tripped. Due to a faulty ALCI plug, your space heater doesn’t get the electricity you need to turn it on the heater.
First off, inspect the ALCI plug for damage. If it gets defective, replace it with a new one. On the other hand, you should reset it by pressing down the reset button if the ALCI plug doesn’t get faulty.
4. An Overheated Unit
Every space heater comes with an overheating protection feature. If your heater gets overheated, the safety switch of your heater will automatically turn off the unit. Your space heater may overheat if the air intake and outlet grilles get clogged by dirt and debris.
In this case, unplug your space heater from the electric outlet and leave it for a few minutes to cool down the unit. Then, use an air compressor to blow out the dirt and debris that blocks the air intake and outlet grilles. Now, plug your unit into an outlet and turn it on.
5. Maybe The Safety Tip-Over Switch Get Activate
Like other electric portable heaters, the Delonghi heater also features a safety tip-over switch. It will turn off your heater automatically if the space heater tips over or are positioned improperly.
Fixing this issue is simple. Just restore your space heater to the vertical position, and it will take just a few seconds to turn the unit on again.
DeLonghi Ceramic Heater Error Codes
PF or HT are some error codes that will display your Delonghi space heater. If your heater shows the error message PF, understand the temperature sensor of the heater is not working properly. On the other hand, your heater gets overheated if it displays this error code HT.
In the case of fixing the temperature sensor issue, first, check the temperature sensor and find if it is faulty or not. Here we recommend you call customer service for this job.
In contrast, make sure you don’t cover the heater if you mounted it on the wall to clear the HT error message. Alternatively, ensure you assemble the heater feet properly if you want to use the heater on the floor. It will help to let the air pass through the unit.
