If your unit is still within its warranty period, it’s important to contact Rheem directly or visit their website to initiate a warranty claim.

When you call a professional technician, inform them about your warranty coverage and provide any necessary documentation. This ensures that the technician can work within the terms of the warranty and potentially save you money on repairs or replacement parts.
