Roper rex6634pq0 won't start, buzzes, gets hot on surface

Solution #1 makes no sense as a dryer does not have a water pump!

But the exact same problem happened to my same model dryer. Pull out from wall. Remove lint filter. Take out two screws holding top to lint filter casing. Pry up top at the front (pops out of two plastic retaining dowels and is hinged on the back so you can tip the top up). Remove front panel by taking out two screw-bolts at top of backside of front panel and lift up -- careful to support drum as you do, as the front part of the drum is supported by the flange built into the front panel. Check:

1) Is belt broken (the incredibly skinny belt that runs around the middle of the drum, not the rubber track at the back of the drum). If belt is broke, replace. New belt at internet parts stores is about $10 bucks.

2) If belt is not broke, get down on belly with flashlight and find the spring-loaded wheel that keeps the belt snug against the motor pulley -- push on the spring-loaded wheel and slip the belt off.

Now try to spin the motor pulley by hand. If it turns freely in both directions, it is probably good and the problem might be in the start switch (don't know how to test that).

If the motor pulley does NOT turn -- or is very hard to turn and binds -- the motor is dead. Probably the bearings burnt out (that's what happened to mine after only 4 years of light use). You have to remove the back panel to replace the motor, but it's a simple job if you know what a screwdriver and socket ratchet are for. New motor at internet parts stores is about $80 bucks.

If your water pump is free of debrees then it's time to buy a new motor.
