I was working as a home service technician when a customer called in to order a collector pan with a seal. The customer explained that the seal on their current pan was broken and needed to be replaced. I asked the customer for the model number of their current pan and confirmed that they needed a replacement seal. I then went to the warehouse and retrieved the collector pan with the seal. I installed the new seal and tested the pan to ensure it was working properly. The customer was happy with the service and thanked me for my help.
