The turntable motors cannot be lubricated, only replaced. The popping noises you mention, is that from the motor or from the microwave arcing??? Unplug the turntable motor and put a cup of water into the unit and run it for a little bit and listen, if it is stil popping you may have other issues.

H95, H97, H98 or H99 mean that there's a problem with your inverter, magnetron, or digital programming circuit.
Due to the lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

The turntable system
consists of the motor, the coupler, the turntable support with rollers,
and the tray.
You can see and hear a video of how a turntable motor should
sound when you rotate it by hand.
If
yours is not set to be off via the control panel, and it won't rotate
or it sounds like it's grinding, etc., you may have a bad motor or
plastic coupler.
To
replace either, you need to unplug power, then remove the bottom cover
of the oven.
You can order
parts for this brand from Encompass (formerly Tritronics). Or you can call them toll-free at 866-779-5835.

Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.
The cost of the magnetron is about 95% of the cost of a microwave oven.
Most people don't, for this reason, replace the magnetron, they replace
the whole oven which is probably what you will end up doing.
There is a possibility that the circuit that provides power to the
magnetron is faulty and you need to take it apart, find the proper
electrical leads and test them with a volt meter. To do this you have
to remove it from its mounting and take it apart. It is a fairly
lengthy process however.

Sounds like the magnatron (the bit that creates microwaves) could be goosed. Remove outer cover ( Isolate from the electric supply then remove screws at bottom on the sides).
Find big lump that says on magnatron with model nos etc on, any good electrical supply shop ( Maplins etc) should stock new one.
It is easy to change. It took me about half an hour having never done one before.
Buyer beware the price of the parts could be in excess of a new microwave.
