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.
