How To Test a Beko Vented Tumble Dryer Heater System, NTC Sensor & PCB

Comprehensive Guide to Testing a Beko Tumble Dryer Heater System & PCB

In this in-depth guide, we will teach you how to repair a Beko tumble dryer. We have created several other videos and guides which you can find on our website or YouTube channel covering topics such as how to replace the belt, how to test the capacitor, how to service and maintain the machine, and much more. Today, we will focus on diagnosing and fixing issues related to the heating element, the NTC sensor, and the thermostat.

Please remember that, when working with any electrical appliances, safety should always be your top priority, and we also suggest you watch our video.

Safety First!

• Unplug your Beko tumble dryer before starting work.
• Organize screws and parts meticulously to avoid confusion during reassembly.

Tools You'll Need:

• Screwdrivers (various sizes) or chargeable drill with correct extensions (if you have one).

Testing the Rear Heating Element and NTC Sensor

First, start by removing the rear cover of the machine. This will expose the heating system. Once you have removed all the screws from the back plate, you can gently pull it off. Here, you will find the heating element, an NTC sensor, and a thermostat.

The heating element has five wires. Behind it is a terminal block that you can disconnect. Additionally, you will see a cycling thermostat and an NTC sensor. Disconnect the wires so that you can test the two sides of the element.

Diagnosing the Problem

With the wires disconnected, you can now test the element. One side of the element has high heat and the other has low heat. Disconnect the two plugs and test the element for continuity.

From the blue wire to the black wire, there should be continuity, and from the blue wire to the white wire, there should also be continuity. You can use Ohm's law calculator, available for free on Google, to calculate the ohms resistance in wattage terms, we use this site: https://ohmslawcalculator.com/ohms-law-calculator

If the readings are about 40 ohms from the blue wire to the black wire, and about 95 ohms from the blue wire to the white wire, the combined wattage of the element is around 2 kilowatts, which is correct.

Next, test the thermostat for continuity by testing from the blue intake to the blue on the meter. If there is continuity, the cycling thermostat is functioning correctly.

Remember to use your full model number from the identification plate when obtaining parts for your tumble dryer from our website.

Testing the NTC Sensor

The NTC sensor, while it may look like a thermostat, functions differently. Testing this component will be slightly more challenging.

Remember, safety should always be your primary concern when working with electrical appliances. If you're still experiencing issues after following these steps, we recommend contacting a professional for further assistance. They will have the necessary expertise and tools to diagnose and fix the problem, ensuring your Beko tumble dryer is back to its optimal working condition in no time.

Checking the Front NTC Sensor and Circuit Board

Now that we've tested the rear heating element and NTC sensor, we need to check the front NTC sensor. To access it, remove the top cover of the machine by unscrewing the three screws holding it. The NTC sensor measures the airflow inside the drum and the circuit board then adjusts the temperature accordingly.

Set your multimeter to ohms and test the sensor. The manufacturer states that this sensor should have a resistance of about 19.5 ohms at 25 degrees. If the readings match or are close to this, the NTC sensor is working correctly.

Next, let's look at the circuit board. If you've checked the wiring from the plug all the way to the heater and it's intact, then there is a high chance that the circuit board may have a faulty relay. To access the circuit board, you will need to disconnect all the connections and remove the circuit board from the plastic mounting.

Testing the Circuit Board Relays

Once you've removed the circuit board, you will see several relays. The challenge here is to figure out which relay is causing the problem. Unfortunately, without removing the relays, it's impossible to test them. However, once you have the relays out, you can check them for continuity if you have the right voltage to activate them.

If you're not familiar with how to replace circuits and relays on printed circuit boards, we recommend you watch our video or seek help from a professional.

Reassembling the Beko Clothes Dryer Machine

After you've completed all the tests, it's time to put the machine back together. Reconnect all the wires, replace the circuit board, and screw back the covers. Remember to clean all the dust before reassembling as it promotes fire and reduces the life of the machine.

Finally, you want to check if the machine is drawing the correct amount of power. The machine should draw about 8.6 amps which equates to just over 2 kilowatts of energy. If the machine is drawing the correct power, the heating system should be working correctly.
