SOURCE: CIRCUIT BREAKER TRIPS AFTER 5 MINUTES.
Hello dale210mile,
Based on your problem description, it is possible that your circuit breaker itself is on its way out.. ( they do go bad sometimes) but before going that route, I would make sure that ALL wiring connections are tight ( meaning shut off the circuit breaker and make sure every electrcial tie point is snug and that you don't have a 'high impedance junction' somewhere in the power feed to the dryer. When you say the heating element 'appears' fine.. not sure what that means exactly but depending on the model.. you should be able to measure its cold resistance with an ohm meter and it should fall within manufactures spec.. A visual check of the heating element really won't tell you much unless it has shorted and you see a burn mark on it.. The mere fact that it runs OK for 5 minutes and then trips the breaker leads me to beleive that it may not be ok..but it is important to rule out the other hardware ( wire terminations etc) before going that route. One test you can try.. if after you've checked all the wiring etc..try running the dryer with no laundry in it .. ( just to verify that the additional load that the motor adds to the entire current draw isn't taking it over the top...) Hope these suggestions help you zero in on the solution..
Good Luck
Rick

No way to know unless you do some checking. This video shows how to get into the machine: HERE
I have a repair manual that features the same basic style of dryer you may want to take a look through: HERE

SOURCE: trips
The switch could be bad. Make sure there are no clogs anywhere that could be causing it to overheat. Try to bypass the switch and run it just long enough to see if you can go longer than the normal 5 min. you're getting. If you can then replace the trip switch. Do not continue to use the machine without the trip switch operating properly or it could catch on fire.
SOURCE: AC runs for 5 minutes and then circuit breaker
What else do you have running on hydro while AC is running? Such as coffee maker, microwave, water heater, fridge. That 30 amp breaker is your main breaker I assume, or breaker on pole your plugged in to. Keep in mind your AC will normally draw approx. 15-17+ amps momentarily when compressor kicks in to cool, then drop back to 12-15 amps when running normal. If your AC is drawing too much current, then you would only normally trip 20 amp breaker for AC in your panel. Try switching other appliances to gas operation while running AC, such as water heater, and fridge. Make sure incoming voltage is up to specs as well . (115-120 volts)
If water heater takes 5-8 amps, and fridge takes same when they are calling for power, you'll be close or over the 20amp mark when you consider your on board converter etc. as well. That only leaves approx 10 amps for AC that requires approx 15 amps to run, and up to 20amps when compressor kicks in. If you switch all those other items over to propane, and it still happens, then a current draw test should be done on AC unit to see if perhaps a capacitor is faulty, or possible compressor faulty.

Breakers trip because of heat.
When heat from wire exceeds breaker rating, it trips.
Something is causing heat on the wire, wire is too small for the amp draw, there is short circuit, or breaker is bad.
Replace breaker and/or test wire.
Put amp-meter on wire and read amp draw through wire.
Amps cause heat. That's why high voltage lines from power station are high-volt-low-amp so there is no heat loss with long distance transmission, until transformer at home converts electricity to lower volts and high working amps with enough power to run electrical devices.
Same is true for AC and DC circuits.
If amp reading on wire exceeds rating on breaker for length of time, then breaker will trip.
The fact that the breaker lets current (amps) to flow for a period of time before tripping is because the breaker is probably rated for slow-acting, or it takes a while for amp draw to heat the wire.
Following image shows amp-meter that clips over wire to get amp reading.
