Lasko-brand space heaters with ceramic heating elements are designed to be portable, efficient and easy to use. If your Lasko space heater fan doesn't work, it's possible the heater's ceramic element has failed, or there may be another problem. In either case, Lasko prescribes a few troubleshooting techniques that you can perform at home. If these troubleshooting techniques do not solve your problem, call a qualified Lasko technician. Further tampering with your Lasko ceramic-element space heater may void its warranty or damage the unit.

Step 1

Unplug your Lasko ceramic-element space heater. Plug another appliance into the same outlet. If the second appliance does not operate, the problem lies with the outlet and not with the Lasko ceramic heating element. Plug the heater into a working outlet to return it to normal working order. If the second appliance operates normally, plug the Lasko ceramic space heater back in, turn it on and move on to Step 2.

Step 2

Check the temperature setting. Many Lasko ceramic personal heater models come with internal thermostats. If the temperature in the room matches or exceeds the preset temperature on the space heater's thermostat, the Lasko heater will not turn on. Raise the heater's temperature setting and the Lasko heating element should engage again. If it does not, move on to Step 3.

Step 3

Leave the Lasko ceramic heater to cool down for an hour or so. The unit may be too hot. Lasko heaters have automatic shutoff devices to prevent the heaters from overheating and posing a fire hazard. Move the Lasko heater to a location with plenty of space around it to facilitate adequate air circulation. Turn the space heater back on. If it does not resume regular function, turn the unit off and move on to Step 4.

Step 4

Clean the unit. Dirt buildup may cause your Lasko heater to run for a few minutes and shut off, then repeat the cycle repeatedly. Unplug the unit. Attach the brush attachment to your vacuum cleaner's hose. Vacuum all elements of the surface of the Lasko ceramic heater. Brush away any stubborn dirt buildup with an old toothbrush. Wipe away remaining soil with a soft cloth. Plug the unit in again. If the personal heater does not function normally, move on to Step 5.

Step 5

Call Lasko Technical Assistance at 1-800-233-0268 Monday through Friday anytime between 8 a.m. and 5 p.m. to determine further action.
