A what is the current in the element when it is connected to 240 v.

Clothes dryer heating element resistance. B how much charge passes through the element in. A bad heater relay blown thermal cut off fuse faulty thermistor broken operating thermostat or failed high limit thermostat can also prevent the dryer from heating. 279838 dryer heating element 3977767 3392519 thermostat fuse kit heating element appliance dryers parts replacement 3403585 8565582. Since we know that the hot water electrical circuit feeds 220 vac to the 16 ampere heating element the resistance of that element is equal to 1375 ohms.

We can round that number up to 14 ohms. So i suspect your heating element has some inductive quality you are not measuring with your meter or it was still connected in the circuit. 45 out of 5 stars 30. Otherwise your 30 amp dryer breaker would be tripping.

Resistive elements dont normally drop in resistance. If you receive a reading of infinite resistance then your heating element is no longer functioning properly and you will have to replace it. Attach the black and red multimeter probes to the leads on the heating coils. Start by taking the metal ends of the multimeter leads and pressing them on top of the 2 leads positioned in the top of the heating coil.

The dryer must have 220 240 volts when checking across the two outside terminals of the terminal block or it will not heat. Find the heating element on your dryer. An electric clothes dryer has a heating element with a resistance of 96 ohms. If you put 4 ohms on 240 volts you get 60 amps.

In order to find the resistance of the heater element from the above described section we must algebraically modify the formula to read r va. Check the wiring see if the circuit measures a low resistance to the dryer case indicating a short.
