The electric heater fan is used for pushing hot air out of the unit, which causes the backdraft to pull new air in. The air is circulated this way to shield the unit from overheating and assist it with maintaining the best possible center temperature. At the point when the fan stops working, the air will simply sit and get stagnant, causing it to eventually overheat and wear out. You can arrange replacement parts on some heater units directly from the manufacturer. Several main things could be causing your fan to not operate appropriately, which includes, but is not limited to, bad wiring or connections, a failed temperature gauge, or a dead fan motor.
- The first thing to do is use your hex driver or screwdriver to open the case so you can see the electric heater fan. Use your voltage regulator to carefully check the connections, starting at the circuit board and moving to the fan and thermostat. Find and single out the pain point, where the lines are not getting the correct voltages. Your readings toward one side of the circuit should be the same on the opposite finish of the same circuit except if it goes through a resistor. A resister can change the voltages between two connections to forestall overcharging specific components in the device.
- A few units use a temperature controlled electric heater fan. This means that the fan doesn’t turn on except if the temperature hits a certain level of heat yield. You can test the fan itself by connecting it to a life force source, and you can do this with several wires connected to the force source. If your fan normally doesn’t come on until after the heater gets hot, at that point it could be the temperature gauge. You can also test these connections with your voltage regulator to check for functionality. If the unit does turn the fan on because of the temperature gauge, and it is a failed circuit, simply use a soldering firearm to replace the part.
- If you test the electric heater fan and it does not read as a finished circuit, the motor is likely worn out. Simply eliminate the fan from the housing with your hand tools and use the soldering weapon to disconnect it from the board. Turn around this cycle to institute your new fan and mount it back into the housing. Be certain it is made sure about appropriately to avoid the fan from pulling random wires into the blades. Make certain to check any resistors with your voltage regulator as well. If these have been internally worn out, the unit still will not work after the fan has been replaced.
- Once the temperature gauge and the electric heater fan have been checked and replaced, if needed, close your case back up. Make certain to place wires and parts back where they originally were to forestall fire and electrical hazards later on.
