Tenant Notice to repair or withhold the rent

[Viral Patel]

Hello All,

We have a tenant in Dallas and one of the tenant on lease send a written notice stating if we do not repair following items she will not pay rent for next month. 

Window in master BR/minor fence fix/range for burner.

Question/Suggestion:

1. How or what should we reply to tenant or do we need to reply her?

2. Can tenant hold rent for landlord not fixing minor stuff? 

Thanks for your suggestion and guidance/ I am surprise, that this tenant never paid rent on time plus give us notice.
