How do I know if my heat exchanger is bad?,
you can pay attention to the following common symptoms:
1. The water is not hot: It might be due to improper adjustment of hot and cold water, unconnected power supply or damage to the electric heater.
2. Excessively high outlet water tank temperature: It might be due to improper adjustment of the temperature controller or adhesion of the contacts.
3. No water in gas water heater heat exchanger: Check if there is water in the water tank(water heat exchanger).
4. Loose power cord: Ensure that the power connection is good.
5. Thermostat failure: If the thermostat is damaged, it may need to be replaced.
The problem can also be preliminarily judged through indicator lights:
1. The heating indicator light is on but it cannot heat up: This might be caused by poor contact at the plug-in end of the heating tube or damage to the heating tube.
The correct way to handle it is to ensure that the high-temperature wire of the heating tube is tightly inserted and to determine whether a new heating tube needs to be replaced.
2. The heating indicator light is not on and it cannot heat up: This might be caused by the temperature controller burning out or the connection terminal of the temperature controller being disconnected.
At this point, the thermostat needs to be replaced.
3. The heating indicator light remains on and the heating continues: This might be caused by a problem with the contact surface between the temperature
sensing surface of the thermostat's probe and the electric heating tube. You can try reinstalling it to restore the indicator light to normal.
If any of the above problems are found, it is recommended to contact professionals for repair. At the same time, when using heat exchanger gas geyser,
regular cleaning and maintenance should be carried out to prevent malfunctions and extend the service life of the water heater.
