A dryer that shuts off before its cycle is over is a frustrating problem. Here’s what to check in order to solve why a dryer is not completing its cycle.
Tripped or Bad Breaker
A dryer that shuts off mid cycle might be due to a bad or weak breaker. Find the breaker box and flip the breaker in order to reset it. If the dryer controls are now on, then the breaker might be bad and will need to be replaced.
Dirty or clogged venting could be the reason why the dryer is not finishing its cycle. The dryer could be overheating due to air flow restriction, causing it to shut off before its cycle is complete. Check the dryer for lint accumulation inside the venting or for kinked or crushed venting that could be restricting air flow.
Be sure to check the outdoor venting as well to make sure it is free from any plants and weeds which could block the opening. Sometimes a bird or other animal will choose to make a nest inside the venting which can also block air flow. To prevent unwanted critters, install a pest or bird guard or louvered hood to the outside dryer vent.
Dryer Power Cord
Inspect the dryer’s cord for brown or discolored tines which could indicate a bad cord that is not providing the correct voltage.
Located on the back of the dryer, the terminal block is a safety part that prevents electrical surges and attaches to the dryer’s power cord. Check for brown, discolored or broken wires and replace the entire part.
A terminal block kit comes with all the parts needed to replace any part of the terminal block.
If a hum or hesitation is heard before the dryer starts up, this could be an indication of weakening dryer motor. If the dryer shuts off, but can be restarted after a 30-minute cool down period, this could also indicate a bad motor that will need to be replaced.
