Water Heater Repair Tutorial: Temperature Sensors ...

27/08/2019· Before you get into how to test the temperature sensor, try power cycling the unit. Put the gas control knob to the “off” position, wait a few minutes, and then try to light the pilot as normal. If the unit doesn’t come on and still codes, then you need to take the gas valve apart. Most newer water heaters use Honeywell gas valves. The Honeywell gas valve has a front, middle and back with temperature sensor …

What Is The Output Of Mq2 Sensor?

People Also Asked, What is the output of gas sensor? The MQ-6 can detect gas concentrations anywhere from 200 to 10000ppm. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.
