Weak heating is usually a bad magnetron.

The manual tells me to test the product by heating a cup of water for 30 seconds

I usually will test a cup of water for 60 seconds and it should be hot enough that you would not want to leave you finger in the water more than a couple of seconds. It would not be hot enough for most people to use for coffee or some other hot beverage but it would be hot enough to burn your finger if you leave it in there for very long. If it is still lukewarm after running for 60 seconds you probably have a problem with some of the major components and depending on the age of your microwave it might be cheaper to replace the microwave with a new one. Hope this helps you!

LG microwave intermittently runs

I would try troubleshooting the "defrost circuit". The behavior sounds like the microwave is cooking in the defrost mode, where it actively cooks then stops allowing the food to rotate and the heat to spread then actively cooking again.

Microwave made a loud grinding noise while heating a cup of coffee for 1 minute,now everything is shut off. We checked the curcit breakers all ok, and there is power going to it!

see this causes and fix it. God bless you
Turntable Motor If the microwave is loud or noisy the turntable motor might be worn out. This is a common problem and relatively easy to replace.
Stirrer Motor If the microwave is loud or noisy the stirrer motor might be worn out. The stirrer is a metal blade which slowly turns around, deflecting the microwave energy in a random pattern inside the microwave oven. As the motor nears the end of its useful life it begins to make grinding noises. The microwave will not heat food evenly without this stirrer, the motor should be replaced.

Exhaust Fan Motor If the microwave is loud when running the fan motor might be

Magnetron If the microwave is loud or noisy only when cooking, the magnetron tube might be defective. The magnetron uses high voltage, high current DC power to generate the microwave frequency that cooks the food. Under normal circumstances the magnetron is nearly silent. However if it is damaged or nearly burned out it can begin emitting high pitched or growling noises. It's not normally dangerous to use a microwave oven when it makes these noises, but they are an indication that the magnetron is almost dead and will need to be replaced.

Heating the cup more than coffee

make sure the stirrer motor located under the outer cover that distributes the microwaves is turning otherwise you will get hot and cold spots in the oven cavity

Everything on oven appears to work, but does not heat.

from what your describing it sounds as if you have burnt the antenna off of the end of the magtube if this is the case if your microwave is no longer under warranty due to the cost of the part you may be better off to purchase a new microwave.

It is your cup. The handle density or moisture content of the handle is causing the mwave to heat it. The rest of the cup contains a liquid (coffee?) that is absorbing any heat generated in the body of the cup. Use a different cup!

I have an Amana Radarange Microwave Oven Model #44-9 that I purchased in 1976. Accidentally I used the microwave instead of the timer for 30 minutes and about 25 minutes into the cooking I heard a pop. ...

Is that model number RR-9?

You can find and order that part (# AP118264) here.

I just hope your magnetron is not blown, too. (Does it still heat?)

You can use a microwave-safe plate in the meantime.

Everything works...Except for actually heating the food

It has a bad magnetron. This is the tube that provides the microwaves to heat the food. Not too easy to replace yourself but it can be done. Cost of magnetron is probably less than $50 or $60.

Panasonic Microwave NN-A770S getting hot on right side externally

If you described this to Panasonic very carefully, and they said it's normal, then I would say keep using it until such time that you get other symptoms. The inverter has some parts mounted on a large chunk of aluminum called a heat sink. It draws the heat out of the parts and the heat radiates and/or convects away. This keeps the circuit parts from overheating. As long as you have good air flow through the vents, it sounds okay.

Mwave made loud buzzing noise then didn't heat up anymore

When there's a loud buzz like that, it does not heat, and does not blow the fuse, it is usually a defective magnetron. Did it sound something like someone making a "gurgling" sound into a coffee cup? I think this has a a one-year warranty, with n five-year warranty covering the magnetron. You can find a local Amana-authorized servicer here:
