Warm air is not hot, but the water temperature is high. Why?

Recently, the water temperature reached 105 twice, and the warm air was not hot, as if the electronic fan had stopped working, but it was not always like this. What's the problem? 1, the warm air is not hot. Usually the small water tank is blocked. Generally, it can be solved by dredging. 2. High water temperature means much higher than usual, or slightly higher than usual. If it is slightly higher than usual, you can check the water tank to see if there is antifreeze. If the temperature is always high, check the temperature control switch of the fan. The phenomenon you mentioned may be caused by the following reasons: 1, insufficient cooling liquid 2, pump failure 3, poor water temperature sensor 4, and poor temperature controller 4. It is necessary to check the working condition of the electronic fan system. Is the fan motor broken? 1. There is something wrong with the electronic fan temperature control switch. Check it. 2. Excessive temperature causes the air storage tank of warm air to hold its breath, resulting in air resistance. Loosen the vent bolt of the small heater water tank and tighten it. 3. If the temperature difference between the inlet and outlet pipes of the large water tank is not large, it can be considered that the thermostat is ok. @20 19
