We get F45 when it shuts off early before the cycle is finished.
For the F45 code. Summary of Possibilities from below reading: 1) Clogged exhaust vent 2) Loose wire connections between Main Control Board
(#6 on exploded view in link below) & Blower Motor Control Board
(#17 on exploded view in link below) 3) Failed blower motor control board

Might seem like a lot but it's really not
This is a copy & paste.
On this type of dryer the F45 indicates a Blower Motor Control Board Speed Sensor error. This can be caused by a clogged exhaust vent.
I recommend checking this issue first.
You can disconnect the flexible vent behind the dryer and let it vent directly into the laundry room. If the dryer runs normally and does not display the F45 error code, then you likely have a clogged or restricted exhaust vent to the outside of the home that is causing this problem
If you still get the F45 code with the dryer venting directly into the room, you could have the following problems:
Restriction or clog in the blower housing.
Loose wire harness connection between the main control board
(#6 on exploded view link below) and the blower motor control board
(#17 on exploded view link below)
.
Loose wire harness connection between the blower motor control board
(#17 on exploded view in link below) and the blower motor.
Defective blower motor.
Failed blower motor control board.

Here are some troubleshooting tips to check for these types of failures:
Check the air flow out of the exhaust vent at the back of the dryer.
Unplug the dryer
and check for restrictions and lint buildup inside the vent on the back of the dryer.
NOTE: Be careful, metal edges on the dryer can be sharp.
Check the wire harness connections between the main electronic control board
(#6 on exploded view in link below) and the blower motor control board
(#17 on exploded view in link below) in the console of the dryer _(with the dryer still unplugged)._ The first image below describes the procedure for accessing the control boards in the console. Unplug and replug the wiring connections between the control boards to make sure that they are secure. Reassemble the dryer and test it. If it runs properly, then a loose connection could have been causing your problem.
