Is Your Infrared Heater Faulty? Discover Why it's Not Working.


Common Issues With Infrared Heaters

Infrared heaters are a popular choice for warming up spaces efficiently. However, like any other appliance, they can encounter problems from time to time. Understanding the common issues that can arise with infrared heaters can help you troubleshoot and get them back up and running quickly.

Here are some key points to keep in mind:

Uneven Distribution Of Heat

  • One common issue with infrared heaters is an uneven distribution of heat. This can result in certain areas of the room feeling warmer than others. Here’s what you need to know:
  • The placement of the heater plays a crucial role in ensuring even heat distribution. Make sure that the heater is positioned in a central location in the room and is not obstructed by furniture or curtains.
  • Check if the reflector or emitter of the heater is clean and free from any obstructions. Dust or debris buildup can hinder the proper distribution of heat. Regular cleaning can help resolve this issue.

Overheating And Shutting Off

  • Another issue you may encounter with infrared heaters is overheating, causing the unit to shut off unexpectedly. Here are some considerations:
  • Overheating can occur due to a blocked air intake or exhaust vent. Inspect the vents and ensure that they are not obstructed by any objects. Keeping the area around the heater clear will promote proper airflow and prevent overheating.
  • Check that the thermostat is functioning correctly. An inaccurate thermostat can cause the heater to run continuously and overheat. Consider replacing the thermostat if necessary.

Malfunctioning Thermostat

  • A malfunctioning thermostat can be a frustrating problem with infrared heaters. Here’s what you should know:
  • If the heater is not reaching the desired temperature or is cycling on and off erratically, it could indicate a malfunctioning thermostat. Consult the manufacturer’s instructions to recalibrate or troubleshoot the thermostat.
  • If recalibration does not resolve the issue, you may need to replace the thermostat altogether. Contact the manufacturer or a professional technician for assistance.
