Why do you need a stove rheostat?
I started the car in the evening, started it, and smelled something burning. The heater was turned on at first speed and when I started it, apparently all the energy was spent to start the engine, but the heater motor did not start. As a result, the heater heater resistor burned out. I turned on the 4th one, it works. And the stove fan works at 4 even without a resistor. Just don’t know why a turbo aircraft is needed at all)
The photo shows that the thermal fuse is located by bending it as close as possible to the heater resistor coil. If the resistor is heated to 117 degrees, its internal circuit melts and breaks. The same thing can happen when soldering a new one. But in fact, it burns out not from temperature, but from increasing current strength when the stove fan cannot move. When the fan cannot move, the load on this fuse increases to 17 amperes.
removed resistor In fact, the resistor itself rarely burns out; the shiny part soldered to pin 4, called a thermal fuse, burns out. Such fuses are still installed in irons and refrigerators. And since this is a fuse, it’s very easy to check whether the resistor itself is working; take any piece of wire and try to short it with a “bridge”. That's exactly what I did. I turned the heater on to first, shorted it out, it works at all speeds. If it works, then it's the fuse. We go to the radio parts store (“World of Electronics” SAMARA on Fizkulturnaya Street) and buy a new one for 15 amperes 117 degrees for 25 rubles. Solder in a new fuse. When soldering, do not overheat, overheating more than 117 degrees will cause the fuse to fail! You need to solder with a heat sink. Overheating will cause the part to become unusable. We put it in place under the glove compartment shelf. Voila, the stove works on all 4.
