What does a capacitor do in a tumble dryer?
The motor on a tumble dryer is an induction motor and does not usually have brushes, requiring a capacitor to supply current to one of its windings. As the capacitor ages over time, its performance can deteriorate progressively, before eventually failing altogether.
How do I know if my dryer capacitor is bad?
Testing a Capacitor To test the capacitor, you will need an ohmmeter. When hooked up to the terminals, the ohmmeter should register a low reading that increases steadily. If the needle doesn’t move or if there is no reading at all, the capacitor is bad and should be replaced.
How do you test a dryer capacitor?
To test a capacitor to see if it is working, you will first need an ohmmeter/multimeter. You will be taking a measurement/reading of the electrical resistance. The reading on your multimeter will tell you if the capacitor is working properly or needs to be replaced.
Do dryers have a capacitor?
Many tumble dryer motors use a capacitor start and if the tumble dryer capacitor goes faulty it may not produce the big kick of electricity which is needed to jump start the motor.
Does a tumble dryer capacitor have polarity?
This capacitor is used to couple AC from the supply across one winding to the other. It is not polarised and can be fitted safely in either direction.
What does uF mean on a capacitor?
uF refers to the size of the capacitor. Capacitance is the charge that is necessary to raise the potential of a body one unit. A capacitance of 1 farad (f) requires 1 coulomb of electricity to raise its potential 1 volt (v). 1 micro farad (uF) = 0.0000001 F.
What are the 3 connections on a capacitor?
A cap with 3 connectors is a combined start/run cap with an S and R terminal and a COM terminal. If you’re converting to using separate start and run capacitors then you will simply use that original COM wire to feed separate Start (previously the S wire) and Run (previously the R wire) capacitors.
Can a tumble dryer capacitor be dangerous?
Tumble Dryer capacitor can be dangerous. It can hold an electrical charge indefinitely even when not connected to a power source. Never touch the terminals of a capacitor until you have discharged it. Never assume a capacitor has already been discharged (Even the New Ones!).
How to replace the capacitor on a Whirlpool tumble dryer?

Why is my tumble dryer not starting up?
Motor capacitors can be a real issue with condenser tumble dryers, as the machine ages the capacitor can fail progressively, causing start-up issues when turning or not starting up at all. Find out how to resolve such issues, in this eSpares video.
