Discover why your space heater is malfunctioning and know what steps you should follow to fix the issue. 

1. You Mayn’t Plug the Power Cord Into the Outlet

Any electric appliance, whether it may be your washing machine or your fridge, you can’t turn it on if you don’t plug it into an electric outlet.

The same thing will happen to your LifeSmart Heater. You fail to turn on your heater if you don’t plug its power cord into an outlet. 

How To Fix:

Plugging the power cord into an electric outlet will be an easy fix for this issue. Also, don’t forget to inspect the power cord or the outlet for damage. If they get defective, change them with a new ones. 

2. Main Fuse Box May Get Faulty

Your LifeSmart Heater won’t turn on if there is no electricity at the main fuse box. In other words, you will get no electric power if the main fuse box is defective.

An overloaded circuit or many appliances running at once can cause the main fuse box to blow out. 

How To Fix:

To solve the issue, locate the fuse box first and raise its cover. Ensure all the trip switches are on. If any of the switches are off, set it to the on position. On the other hand, call a certified electrician if the entire fuse box gets faulty. 

3. Battery Is Gone

If the battery in the remote control of your electric heater is dead, you can’t turn it on. You can figure out whether the battery in the remote control does run out or not by turning the heater on manually.

If the heater functions correctly by using the manual switch, we bet the battery is dead. 

How To Fix:

Just replace the remote batteries with new ones to let your remote control function properly. We recommend you change the battery every six months. Here you can learn how to replace the battery from remote control instructions.

4. You May Set The Thermostat Lower Than Room Temperature

Most homeowners often overlook this problem when their electric heater doesn’t function or fails to turn on. If your room temperature is more than the temperature you set on the thermostat, your heater just sucks. 

How to Fix:

Access the thermostat of your heater. You should remove the cover of the heater with a screwdriver. Then, set the thermostat temperature more than your room temperature or according to your desired level. 

5. Defective Thermostat

And last, but not least- is to inspect the thermostat of your space heater. The thermostat is responsible for controlling or adjusting the temperature of your electric heater.

If it doesn’t function properly, you can’t turn on your LifeSmart heater. And if you can turn it on sometimes, somehow, the heater will keep shutting off a few times later.

How To Fix:

If there is a problem with the thermostat, you should replace the thermostat with a new one. We recommend you call the LifeSmart Support Team for help.
