Dryer won't turn on

Dryer won't turn on Any household appliance can break down over time. It’s good when the reasons are easy to figure out, for example, if the dryer stopped turning the drum or the quality of drying became worse. It is much more difficult to deal with the situation when the dryer does not turn on at all. In this case, is it possible to restore the functionality of the “home assistant” or should we start looking for an alternative in stores? Let us examine in detail this unpleasant problem, from which no one is immune.

What happened to the dryer?

The worst thing you can do in this case is to start panicking and plan radical actions. It is quite possible that the cause of the problem is hidden in a simple lack of power in the house or in a damaged power cord. If the wire is really damaged or pinched by a heavy object, then it must be released or replaced. If the cord is working, then you need to try to connect the machine to another outlet, and also make sure that there is electricity. What to do and check if there is electricity in the house, the cord is in order, but the dryer still does not turn on?

Thermal fuse. This sensor is necessary to protect equipment from overheating, as well as to control the operation of the heating element. Due to the fact that the fuse is located inside the electrical circuit and current flows through it all the time, if the sensor is damaged or overheated, the integrity of the circuit will be disrupted, and electricity simply will not be able to get to the heating element. Therefore, if the thermal fuse is not working, normal circulation of hot air within the system is impossible.It is impossible to restore the unit; you will only have to buy a new fuse and install it in place of the old one.
Start switch. Checking this element of the dryer is very simple - turn on the equipment. If the equipment produces a low-frequency hum, then the unit is in order, and the cause of the malfunction should be looked for elsewhere. If after starting you do not hear any hum or see any reaction, then most likely it is the starting switch that has failed.
Control Panel. Finally, the last thing you should check is the rarest, but still possible, breakdown. The dryer control panel may stop working due to a faulty microcontroller and control board. This could happen due to a sudden voltage drop, a short circuit, or water getting into the circuit. In this unpleasant situation, only purchasing a new unit will help.

The reasons are indicated, let's move directly to localizing the problem.

Testing and changing the thermal fuse

Most often, the fuse is located next to the heating element, so it is easy to find. To check the part, you will first have to gain free access to the heating element, which, depending on the model of the dryer, can be installed in different places. Basically, the heater is located in the back of the case, so the user needs to remove the back panel of the machine, after first removing the clamps from it.

Be sure to unplug the “home assistant” from the network before you begin to disassemble it.

The fuse is installed near the heating element in a small plastic box. It is necessary to carefully open the box and remove the thermal fuse. You need to check its integrity with an ordinary multimeter set to resistance measurement mode.Zero resistance is a sign of a working element, while a break in the network indicates a failed fuse that needs to be replaced with an original spare part. It is better not to settle for analogues with suitable amperes, as they will last you less. dryer thermal fuse

After replacing the unit, a test run cycle should be carried out to ensure that the cause of the problem has indeed been eliminated.

Checking the start switch

You will also have to test the start switch on de-energized household appliances. To check, you will have to partially disassemble the “home assistant”, carefully following our instructions.

Carefully remove the top cover of the case, first unscrewing the two fixing screws from it.
Now remove the screws on the end of the control panel, as well as on the side.
Slowly remove the panel from its seat, being careful not to break the wires.
Locate the back of the starter switch, which will have two or three wires connected to it.

Don't be in a rush to disconnect the wiring - take a few detailed photos first so you have an example at hand during reassembly.

Using pliers, remove the connectors from the terminals.
Now put the multimeter into resistance mode, usually labeled "R1" or "RX1".

All that remains is to check the functionality of the element. If the switch has two outputs, then you need to connect the tester probe to each of the terminals. The device should show infinity. When the test leads are at the terminals, activate the start switch. If the tester shows zero, then everything is in order, if the value is different, you will have to buy a new switch to replace the damaged one.

When the switch has three contacts, you first need to find a terminal of the “NC” or “CT1” type. Connect the tester probe to this terminal, and install the second one to the terminal marked “CO” or “R1”. The tester should display infinity. The further stages of testing are similar - if the multimeter shows zero, then everything is fine, but if the indicators are different, then you need to change the switch.

You should buy original spare parts that will work perfectly with household appliances without endangering them or the user. If you are unable to find such a switch, then it is better to contact the service center so that employees can select the appropriate element for you.

Dryer control board

Unfortunately, if suspicions fall specifically on the control board, then you will not be able to solve the problem yourself, so you will have to call an experienced technician. This is due to the fact that a person without experience and special equipment will not be able to qualitatively test the part and identify the cause of the problem. The most you can do with your own hands is to inspect the board and check it with a multimeter, and then transfer this data to a service center employee.

Very often, problems with the circuit can be seen with the naked eye - burnt contacts and tracks are a guarantee that the unit needs repair or replacement.

Partial disassembly of household appliances and analysis of the control board of the dryer requires special knowledge, so if you do not have it, then it is better not to waste time, but to immediately entrust this work to a specialist. Not only will he be able to carry out a thorough diagnosis using his equipment and special software, but he will also repair the board, if possible, or replace it with a new one.
