Q:

Roper RED4440SQ0. How to replace the timer.

A:

Thank you for your question and I understand your concern.

I assume timer is being set in the "Time" cycle and not the "Automatic" dry cycle. 

You said it gets down to about the 40 minute mark and then it will "just forever". I assume you mean it runs forever and the dryer timer quits advancing when it reaches the 40 minute mark. I assume the dryer will shut off when you manually turn the timer to "OFF" or open the door.

Based on your symptom, it sounds like a timer issue. To properly diagnose the issue will require checking the voltage to the timer motor when it quits advancing across terminals TM and BU on the timer. The timer motor requires 220 volts. On time dry, the voltage should measure 220 all the way through to off unless the timer reaches the wrinkle guard and the wrinkle guard switch is turned on. The wrinkle guard will cycle the dryer off and on for a while until it times out. I added an image below of the wiring diagram so you see the timer circuit. NOTE: I do not recommend making voltage measurements unless you have experience and feel safe and confident in doing so; otherwise I suggest calling a service technician to diagnose and repair your dryer.

To remove the timer, disconnect the power cord from the power source and then remove the panel from behind the control panel.  Pull the timer off the timer. Remove the screws from behind the timer knob and then you can pull the timer out from behind the control panel. 

I hope this is helpful. If I may be of further assistance as more details become available, please reply to this post.
