Recurring electrical issue: Compensate the tenant?

[Garen T.]

Hi

2 months ago my tenant let me know that the Master Bed and Master Bath circuit kept blowing. She would have to reset it, and then it would only stay on for a day or two. I had my service go look at it and they found a plug that was arcing. This is a SFR that is only 4 years old. They replaced 2 plugs and put in a new breaker. It took about 5 days to resolve the issue from 1st telling me, to getting it resolved. The lights were off only occasionally and could be resolved by the breaker.

I got another e-mail from her this past Friday saying that the breaker had tripped again, but now it would not reset. No lights at all in MBR and MBTH. I called my handyman service again, they are bringing in an electrician the best I can get them out is Tuesday at 5pm. 

So, assuming they fix it tomorrow night, it will be 4 days with no power to these 2 rooms. 

Questions: 

1. Anyone know what to look for on this? I'm bringing in the experts, but if you happen to know, it would be great.

2. This is really the goal of my post today. Should I as a good landlord, wanting to do the right thing for my tenant, provide them with a discount on rent, a free dinner, gift card, note in the mail, anything?

The lease is pretty vague on this: I just re-read and the only thing I'm obligated to per the lease is to put them up in a hotel if the entire premise is not livable due to some issue that is not their fault. Nothing is specified as to 2 rooms not having power and everything else is working properly. 

Thanks!
