Lasko appliances such as residential space heaters and household fans are designed to be efficient and durable. For example, the appliance life expectancy of space heaters is between 8 and 15 years. Troubleshoot your Lasko appliance malfunctions that you can repair yourself and keep getting the most out of your product.
Your Lasko heater doesn't start—Your appliance runs on electric power and will not turn on if there's an issue with the wiring or an electrical control failure. Typically, defective components such as a malfunctioning thermistor are a contributing factor.
Your Lasko fan starts, but it’s noisy—Sometimes, your fan may produce a rattling, cracking or humming sound when it oscillates. Usually, it's caused by loose screws, which may need tightening. If this doesn't alleviate the issue, you can either place your fan on a cushioned surface, such as the carpet, or clean and dust it off to get rid of debris.
The remote control is unresponsive—If your appliance is operated by a remote control, it may become unresponsive if the batteries in the remote are low and need replacing. If you're using new batteries, you may need to replace the remote.
The heater light is on, but it won’t start—The Lasko heater may not start if you set the desired temperature too close to actual room temperature so check the heater temperature setting. If you set the temperature correctly, then you may need to replace the thermostat.
The heater runs for a few minutes and then shuts off—Clean dust buildup and get rid of debris that may be interfering with the electrical control board.
If none of the pointers listed above mitigate the problems with your Lasko appliance, it's possible that you have malfunctioning parts that need replacing.
Replacing faulty parts in your Lasko appliance
Thermostat—Your Lasko space heater likely uses a thermostat to regulate the heat it emits. If the thermostat is doesn’t cycle the heating element on and off to maintain the set temperature, then you may need to replace the thermostat.
Grommets—Problems with Lasko ceiling fans becoming noisy or slow can, at times, be traced back to the grommets. Worn-out grommets can cause the fan to vibrate loudly even if there's no debris present. Replace any missing or damaged grommets.
Capacitor—A blown capacitor could prevent the blades on your Lasko ceiling fan from turning. Shut off the house breaker for the ceiling fan to disconnect electrical power. Check the capacitor using a multimeter. Replace the capacitor if it’s blown.
Hassock top—Sometimes, the hassock top of your Lasko portable fan can break when you're moving, cleaning or dusting it. Loose or broken parts can make the portable fan unstable, noisy or unusable. Carefully loosen the blades and replace the broken hassock top.
