Chunfeng HVAC Company: Sharing experience in troubleshooting and repairing heating problems in winter
When the temperature drops sharply in winter and the heating system is frequently activated, many small problems that are not usually noticed may appear at this time. In order to help you quickly troubleshoot and repair common heating faults, we have specially compiled some practical troubleshooting and repair experiences. We hope that when you encounter problems, you can try to solve them yourself first. Most problems only require simple tools and quick treatment can prevent more serious damage. If repairing it yourself doesn't work, you can contact our professional technical team at any time and we will provide you with comprehensive assistance.
0️⃣ Check heating power supply and natural gas switch
Frequency of the problem：🔥
Repair difficulty：🔥
Fault characteristics：
- Nothing happens after turning on the controller, or the machine starts normally but the flame cannot ignite.
Failure analysis：
Many users may accidentally turn off the natural gas switch before winter or when there are children at home. Especially when the natural gas switch is of different colors (such as red), it is easier to be ignored.
Solution：
- Check whether the heating power is on.
- Check whether the natural gas switch is on. Sometimes the natural gas switch is far away from the heating device, so make sure all switches are turned on.
1️⃣ Flame Sensor is damaged
Frequency of the problem：🔥🔥🔥
Repair difficulty：🔥🔥
Tools required：
- screwdriver
- flashlight
- fine sandpaper
- kitchen paper
Fault characteristics：
- The heating would come on, but would soon go off. It still starts after restarting, but stalls again after a short time.
Failure analysis：
After being used for a long time, the flame sensor may be covered with grease or dust and cannot sense the flame properly, causing the equipment to automatically stop running to avoid natural gas leakage.
Solution：
- Turn off the heating power.
- Open the heater cover and find the flame sensor.
- Use a screwdriver to remove the sensor.
- If there is rust on the surface, you can use fine sandpaper to lightly sand it.
- After wiping it clean with kitchen paper, reinstall the flame sensor.
2️⃣ The filter is clogged
Frequency of the problem：🔥🔥🔥🔥
Repair difficulty：🔥
Fault characteristics：
- The heater starts normally but stops working before the temperature reaches the set value. Usually the machine will stop after running for a period of time and restart automatically several times.
Failure analysis：
A clogged filter is a common reason why your heating system stops working. A clogged filter will cause poor air circulation and cause the blower to overheat, triggering the protective mechanism to stop working.
Solution：
- Replace the filter regularly. Home heating systems usually require filter replacement every 2-3 months.
- Choose the appropriate filter based on your home environment. For example, Chinese families are recommended to use MERV11 grade filters due to a lot of cooking and cooking fumes.
3️⃣ Blower burned out
Frequency of the problem：🔥
Repair difficulty：🔥🔥🔥🔥🔥
Fault characteristics：
- After the heater is started, the flame burns normally, but the blower cannot start and the air does not flow.
Failure analysis：
If the filter is clogged and not replaced in time, hot air cannot circulate properly, causing the blower to overheat and be damaged.
Solution：
- Purchase a new filter and replace it.
- If the blower failure is serious, it is recommended to contact a professional for replacement.
4️⃣ Ignitor failure
Frequency of the problem：🔥
Repair difficulty：🔥
Fault characteristics：
- After the heater is turned on, the igniter does not turn red or the flame ignites.
