It is quite unfortunate that your Lasko heater isn’t working as it should, especially if it is during winter. The situation could be worse if it won’t turn on, no matter how you try. However, the good news is that you can fix this problem by yourself.
Most of the issues you’ll encounter while using the Lasko heater involve maintenance. That means that with routine maintenance, you wouldn’t have to worry about glitches regularly.
Below are the few probable causes why your Lasko heater beeps but does not turn on.
1. Dirty filter
Contrary to popular opinion, heaters come fitted with a filter. This primary purpose is to capture any dirt and debris that would otherwise cause your heater to malfunction. Like any other equipment, you must change or clean a heater filter periodically.
Failure to which your Lasko heater beeps to remind you that there is something you ought to have done. Here is how to go about it:

- Screw open or pry open the back of the heater to reveal its components.
- Locate the filter. You can use the manual to tell exactly where the filter is located in your Lasko model.
- Confirm whether your filter is supposed to be cleaned or replaced from the user manual.
- If you can clean it, run it down a stream of cold soapy water, then rinse it before drying it in the open air.
- If the filter needs replacing, confirm what size and model you need to get from the convenience store.
2. Broken thermostat
A thermostat is one of the essential parts of a heater. Its main job is to tell the temperature so that the heater adjusts itself accordingly. So if your heater doesn’t turn on but keeps beeping, it might be because the thermostat is broken.
Here is how to remedy the issue:
- Unplug the heater and ensure that it has cooled down
- Open the heater by unscrewing the back part

- Check if the thermostat is working fine by using a continuity
- If it keeps breaking, then you need to replace the thermostat. If your heater is within the warranty period, you can replace it for free.
- Check the wall socket.
Your heater can only work if the wall outlet produces enough electricity. So if the heater keeps beeping for whatever reason, it could be that there is low voltage.
Here is how to confirm:
- Unplug the heater from the wall socket
- Try plugging in another appliance to the same socket and see if it works well
- If it doesn’t, then the problem is either the wall socket needs to be replaced or the electricity level is down
- Switch off the main electricity switch
- Unscrew the wall socket
- Confirm if all the wires look fine. If one is burnt, call an electrician
4. Thermal overload
Typically, you are supposed to let your heater cool down after using it for a few hours. However, some models are designed to warn you if the heater is about to overheat.
For example, if you ignore the beeping sound, the circuit breaker will switch off the heater to allow it time to cool down.
Here is what to do in this situation:
- Unplug the heater and allow it to cool down for a few minutes
- Unscrew the back part of the heater and remove it
- Confirm that the fan is not obstructed by anything
- Ensure the thermostats are working as they should be using a continuity meter
- Return the back part to its respective position
- Plug in the heater to check whether the beeping sound has stopped
5. Broken quartz heat tube
Every Lasko comes with a quartz heat tube to help regulate the thermostat. If this part breaks, your heater will malfunction hence the beeping
To confirm whether this is the issue:
- Unplug the heater from the wall socket
- Ensure it cooled down significantly before attempting anything
- Check whether the Quartz tube is in good condition. If it’s not, you have no other option but to replace it with a new one.
- Alternatively, take it to a professional electrician
Lasko heaters are built to last; however, you need to perform routine maintenance to ensure it’s working at peak performance.
