Depending on availability, we use original manufacturer parts or compatible replacement parts. Covered replacement parts carry a 90-day warranty. If a covered part fails within 90 days, the replacement part is provided at no charge. Labor is covered for 30 days; if the part fails after 30 days but within 90 days, labor is charged. No handling fee or separate service-call charge applies when replacing a covered part. Only parts listed on this invoice are covered by this warranty. If other parts break down due to use, age, or another reason beyond our control, regular material and labor charges apply. Clearing of clogged drains is guaranteed for ten (10) days. No guarantee applies to replacement of plastic or glass shelf support basket slides.
