Normally the on-voltage will be about 3 times the threshold voltage being the point the device switches fully off. Triple check the wiring and post a circuit diagram hand drawn, not Fritzing. As mentioned above, the schematic shows the MOSFET wired backwards, which can’t work the heater should be on all the time due to the body diode.

What I noticed is that when i disconnect the 19V supply, the serial monitor shows a steady 0 from the pot read from A0. Is your printer bed rotating? The test code I used is here. I tried at reducing the resistor from 10K to Ohm. If that is a problem, a 10K.

Also the sine wave code is something I found out on one of the forums that was used to demo a bulb going dim and bright slowly. So the heater can be on during reset until the pin 3 pinMode is executed in setup. I need to study more.

Attached is the datasehet circuit just a variation to my prev, this time using a pot. But when I connect the 19V, the values start floating wildly, and thats probably why the thermistor started smoking before I unplugged.

Please point out what you are calling a thermistor on your diagram.

I am using the attached circuit to heat up the 3D printer bed. If you mean that the power resistor heater is not turning off, double check your wiring and the pinout of your MOSFET. This is one of many useful ones.

Ok, once again, thanks for helping out an electrically challenged person. The behavior that you describe sounds like what jremington mentioned in reply 7. IRFZ34N getting too hot. A better choice would be more like ohms, high enough to limit current but datashdet enough to charge the input capacitance quickly as possible.

Agree about the gate resistor. But the thermistor isnt turning off.

The key specification is the value of Vgs quoted in the on-resistance section. A thermistor is a type of variable resistor used to measure temperature. Is the attached looking any better?

Screen Shot at But that didnt make a difference. The thermistor 25W 5. I did connect a 10K from the gate to the ground. In between those two the device can be half-on, meaning it may dissipate lots of power and get very hot – the region of operation you want to avoid.

The gate resitor is way irfz3n4 high. I read serial values and can see that the pot is working. I measured a 2. I am PWMing the pin 3 of the nano.

Here is the code, Code:
