The failure of your Roper dryer to heat up doesn't always mean that it is inoperable. In some cases, it's a matter of checking your power supply, which can disrupt your dryer's heating capability. Your dryer not heating up may also be a problem with the heating element, which is simple to repair. Regardless of the reason, consider troubleshooting such issues before calling a costly repairman. Oftentimes, fixing a Roper dryer that's not heating up can be achieved with a little elbow grease and a screwdriver.
Examine your fuse box for tripped circuit breakers or blown fuses. Replace any blown fuses and reset the circuit breaker. The Roper dryer requires two fuses; check them both.
Examine the gas line for obvious leaks or damage if you have a gas Roper dryer. If there are none, ensure that the supply valve is at the "On" position.
Run the dryer on high heat for three minutes and then turn it off. Open the door and look for the heating element, which should be glowing. If it isn't or you feel no heat whatsoever, the heating element needs to be replaced.
Heating Element Replacement

Open the back access panel, which can usually be done with a flat-head or Phillips head screwdriver.
Locate the dryer's heating element, which is typically on the right side inside a vertical rectangular can.
Unplug the thermal wires, retaining clip and other wires leading to the heating element. This may require the use of a screwdriver, depending on which Roper dryer model you have. Always firmly hold the wires with needle-nose pliers as close to the heating element connection as possible when removing them.
Unscrew the heating element can cover and remove the element.
Replace the faulty piece with the new element and close up the dryer in the reverse order of this section.
