All lights flicker and dryer stops. Unplugging usually helps for a bit, but the problem persists

Unplug it and check the connection inside where the cord attaches to the machine. I have seen these come loose.

Hi and welcome to FixYa, I am Kelly.
Unplug it and wait 20 - 30 minutes. The compresor needs 10 to 15 minuts of off time to re-start. Power losses of less than 5 minutes will cause the compressor thermal overload to cycle repeatedly until something fails or in the case of non-electronic control defrost timers... the next defrost cycle. What happens is the coolant pressures are so high that the compressor can not start. Let it stabilize for 20 - 30 minutes by unplugging it and try it again. If that does NOT work respond here and we will help you.

This is what caused your problem: ever since the electricity flickered this morning like five times

Thanks for choosing FixYa,

Today's dryers have many sensors and a fuse to prevent overheating and possibility of a fire. This is good.
Unfortunately, today's factories are often highly automated, and today's machines seem to collect a lot more lint deep inside because of looser fitting components. This lint seeps into the whole machine, and causes those many sensors to "pop".
Someone needs to dismantle the whole machine and clean out the lint.
Be blessed.

Please check the heat sink and also clean the ram it might sometimes give issues when dust is accumulated there.

Hi, My Hotpoint Aquarius TCD32 0771200901

Tumble dryer stopped working, first a filter care light, so cleaned the filter and now the light comes on but nothing happens. Any ideas? Thanks

maybe low on coolant, check water to coolant ratio.

I have this problem too, I have noticed that when this happens the moisture is high within the dryer. Usually when I open the door and let the steam out and let the dryer cool a bit it stops, but would still like to know why it really is doing this.

CHECK UR FUSES THEN CHECK ALL UR WIRE CONNECTIONS

The filter capacitors in the power supply are going bad. This leads to more ripple in the voltage which is why you see the screen flicker. Sometimes the transformers that drive the lights go bad themselves, but generally when that happens you won't have a backlight. Replace the capacitors with the exact same ratings, except you could go up a bit in voltage, and make sure the temperature rating is 105 C or higher. This will stop the flickering.
