Which way is correct in writing:

Hello Experts,

Which way is correct in writing as I'm confusing with the "Troubleshoot vs Troubleshooting"

a. "I'm so sorry to hear that you have an issue with the Microwave and want to say thank you for the troubleshooting you have done."
b. "I'm so sorry to hear that you have an issue with the Microwave and want to thank you for troubleshoot of the issue before you called me for help."

Thank you,

A is correct.

Troubleshooting is the gerund (-ing) form of the verb "to troubleshoot"

So in sentence A, the verb is conjugated correctly.  In sentence B, you are using the verb in the infinitive (without conjugation) form and that would not be grammatically correct.

a. is correct. However, as it stands now, it is a so-called run-on sentence. A web search for that phrase will give you plenty to study, with the Wikipedia article on it a good place to start:

I suggest rewriting it as:

I'm so sorry to hear that you have an issue with the Microwave. Thank you for the troubleshooting you have done.
