If you supposed to have a dryer--either it is in your lease, or it was at least in how the property was described to you, and therefore was part of why you rented it (and presumably, the amount of rent you pay is based at least in part  on having a dryer)--you could sue the landlord and/or the management company if they will not fix it. You would sue for breach of contract, since they are not providing what you are paying for; you could seek a court order forcing them to fix it and/or compensation for the time period during which it has been unavailable (for example, if you had to pay more to do the laundry outside, at a laundramat, for that increased cost). Unfortunately, a lawsuit is the only way to force the landlord to either address the situation or compensate you, if the landord will not do so voluntarily.The landlord may raise your rent for a new term, even if you did not have a working dryer, unless your unit is subject to rent control ordinances of some sort; if it was, the landlord may only raise your rent in accordance with those ordinances.
