Learn how to set the timer on your Lasko ceramic tower heater, including step-by-step instructions for the 23-inch model with remote. Adjust settings for comfort and energy savings.

Quick Answer

Press the Timer button on the heater or remote, then use the + or – buttons to set the auto-off time from 1 to 8 hours. The display shows the remaining hours.

Why Use the Timer?

The timer lets you run the heater only as long as needed, saving energy and reducing the risk of forgetting to turn it off. For example, set it to shut off after you fall asleep or leave for work.

On the Lasko 23-inch ceramic tower heater, the timer works with both the heater panel and the included remote control, so you can adjust it from across the room.

Common Timer Mistakes to Avoid

Pressing the Timer button once starts the setup mode, but it does not set a time yet—you must then press + or – to choose the hours. A common mistake is pressing Timer and expecting it to start immediately.

The timer counts down in whole hours only. If you need less than one hour, the timer may not be the best option; consider turning the heater off manually or using the thermostat to cycle the heat.

Step-by-Step: Setting the Timer

Turn the Heater On: Plug the heater into a wall outlet and press the Power button on the unit or remote. The display will light up showing the current temperature or settings. Make sure the heater is in a stable position on a flat, level surface before turning it on.
Press the Timer Button: Locate the Timer button (labeled with a clock icon) on the control panel or remote. Press it once—the display will show a flashing number (usually 0 or 1) indicating you are in timer setup mode. If the display does not flash, try pressing the button again. The timer only activates when the number is flashing.
Set the Desired Hours: Use the + (up) or – (down) buttons to adjust the timer from 1 to 8 hours in 1-hour increments. Each press changes the time by one hour. The display will show the selected number and stop flashing after a few seconds. The timer counts down continuously; you cannot set partial hours. For example, 1.5 hours is not possible.
Confirm the Timer Is Active: Once the display stops flashing, the timer is set. The heater will run for the chosen number of hours and then automatically shut off. The display will show the remaining time (e.g., 5 hours left). If the heater turns off unexpectedly, check if the timer reached zero. Press Power to restart and reset the timer if needed.
Adjust or Cancel the Timer: To change the timer, press the Timer button again and repeat step 3. To cancel the timer completely, press the Timer button until the display shows 0 or the timer icon disappears. The heater will continue running until you turn it off manually. Canceling the timer does not turn off the heater—it just removes the auto-off schedule.
