Question about Whirlpool LGR8648 Gas Dryer
Dryer starts no problem heat seems good then heat stops and it blows cool air
Found the coils. Had to pop off the entire front panel. They were then easily reachable.

Back in June I replaced the gas valve coils and that fixed the problem. It appears that when the coils are begining to fail, they'll work only when they are cold. After the dryer is up to full temperature the coils will not open the valve when more heat is needed...at least not until the dryer cools down.
I had this same problem with my furnace flame sensor. It failed in a way that it would only work when it was completely cooled down. Troubleshooting revealed that the furnace was failing at the 5 second "wait for flame sense". At that point the flame would go out and I could not restart it until everything cooled down. Thanks for all the help on this.

I HAD THE SAME PROBLEM. I CHANGED THE GAS VALVE COILS AND IT WORKED FINE.

I am sending you all the possibilities for your problem, check either of these causes ----and than let me know if it is solved----
Power from the house
Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected.
Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable.
On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.)
A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.
