Inspect the electrical socket that the Warmwave heater is plugged into. Warmwave heaters are mounted on walls or ceilings, and have one plug that's used to connect to the electrical power source. If the cord that connects the heater to the power source comes loose from the socket or is damaged, this causes the Warmwave heater to appear broken. If you notice any frays or tears in the cord, wrap electrical tape around it and contact the Warmwave company for a replacement. But do not continue using it, or it could pose a potential hazard.
Remove the Warmwave heater from its mount by unscrewing it with a screwdriver. The mounting system for Warmwave heaters is simple, and no building or construction is necessary to affix the heater to the wall.
Look behind the heater. Inspect the back of the panel for any cracks or fractures that could potentially cause the product to malfunction.
Seal any cracks or fractures in the panel with an epoxy resin. The carbon fiber mat on the inside of the Warmwave heater is responsible for transferring the heat through a controlled environment in the panel. However, if cracks or fractures are present, this means you might be losing some of the heat and, therefore, the room does not feel as warm.
Touch the back of your hand against the panel of the heater. The panels are designed to be heat resistant, so that you can touch them without getting burned. However, if the panel feels cold, this might indicate a problem with the internal mechanism that generates the heat through the panel.
