Why Lifesmart Heater Keeps Shutting Off [4 Easy Solutions]

We’ll now take a look at the solutions that are applicable for each of the different reasons why the Lifesmart infrared heater keeps shutting off.

To choose a solution that matches your situation best, first, you’ll need to identify which of these issues are causing your heater to keep shutting off. 

1. Overheating

The most common reason why heaters shut off is overheating. Your heater will show the E1 error code when it overheats. This fail-safe mechanism is there to protect the heater from damage caused by overheating.

Solution:

To solve this issue you need to turn off and unplug your heater, wait for it to cool down and then plug it back in. When you turn the heater back on it should work just as fine as before.

But this solution is temporary if your heater is placed in a tight spot. When your heater’s air inlet and outlet are blocked by solid objects, that causes poor airflow to the heating system. Due to poor airflow, your heater tends to overheat often.

Make sure your heater’s air inlet and outlet are at least 3 feet away from any solid material that will obstruct airflow.

Now, let’s say your heater is positioned correctly and your heater still gets overheated after starting. In that case, check your heater’s filter. It must be dirty and blocking airflow. You need to clean it to fix your filter.

Take out the filter and check to see if it has a plastic frame or a cardboard one. Cardboard framed filters can’t be reused, so you’ll need a replacement.

Plastic framed ones can be reused. Wash it under a faucet or with a garden hose. Make sure all the dirt is removed and let it dry before replacing it in the heater.

2. Electrical Overload

Another reason why your heater keeps shutting off can be that your heater is being supplied with more voltage than its rating. When the heater is overloaded, the fuse is tripped, cutting off power to the entire unit.

Solution:

Reset the circuit breaker. But if this issue persists, it’s most likely being caused by a broken motor. Heater motors are extremely complicated and if you don’t have any expertise in electrical work you may damage your unit for good. It is better to leave this one to the professionals.

A licensed electrician will figure out which heating component is causing the issue and fix it. 

3. Bad Thermostat

A faulty thermostat can misread temperature and cause your heater to shut down prematurely. And you may notice your lifesmart heater won’t turn on from then. This can happen because of a broken internal gauge in your thermostat. Sometimes due to the bad placement of the thermostat in your home, it functions poorly. 

Suppose, you’ve placed the thermostat at a spot that is usually hotter than the rest of the house. This will misdirect your thermostat into identifying temperature inaccurately. 

Solution:

Make sure your thermostat isn’t broken. You can test the thermostat with a multi-meter. If your thermostat isn’t working properly and gives an abnormal reading on the multi-meter, you’ll need to get it replaced. You can easily find Lifesmart heater parts, which are compatible with your heater in the market. 

Also, ensure that your thermostat is in a place that represents the temperature of the entire room well. Placing the thermostat close to a draft or a hot spot is not ideal.

4. Over Powerful Heater

When your heater is too powerful for your house, the heater will shut off prematurely as the room will heat up very quickly. 

Solution:

You’ll need to replace your heating system as there is no way to fix this improper installation. The heater is too big for your home. You’ll need to get a new one that fits perfectly with your home size.
