In winter, we often turn on the bathroom heater to say goodbye to shivering during showers. However, with frequent use, the bathroom heater may break down. Let’s take a look at how to fix it and some related knowledge.
How to Fix a Broken Bathroom Heater
1. No response when powered on, and indicator lights are off. This situation is usually caused by a blown fuse (FU) on the power driver circuit board. Replacing the fuse should solve the problem.
2. The air output from the heater is significantly reduced. This is often due to excessive dust accumulation at the air inlet, which leads to poor ventilation. Simply clean the air inlet to resolve this.
3. Only cold air is blowing, with no hot air. This indicates that the PTC ceramic heating element is not functioning, often due to overheating, which causes the thermal protection circuit to activate or get damaged. In this case, it is necessary to replace the entire heater.
4. The remote control has lost its functionality. This issue may be due to a damaged infrared (IR) emitting diode or IR receiving unit. It may also be a battery issue. If it’s an IR problem, replace the component; if it’s a battery issue, simply install a new battery.
Precautions for Using Bathroom Heaters
1. Ensure the bathroom heater's electrical wiring is standard. Use waterproof wiring for the electrical connection, with copper core wires not less than 1 millimeter. The power wiring should be routed through plastic conduits and should not be exposed. The switch should be a compliant product with a capacity of over 10A and be waterproof.
2. Avoid frequent switching and vibrations in the surroundings. Do not turn the heater on and off frequently. Additionally, during operation, avoid placing it near where there is significant vibration, as this can affect its lifespan.
3. Purchase a heater according to the bathroom size. When buying a heater, consumers should choose based on the size of their bathroom. For bathrooms under 5 square meters, two-bulb heaters are sufficient, while larger bathrooms should opt for four-bulb heaters.
