The repair cost outside the warranty period usually includes parts costs, labor costs and travel expenses (if the repair personnel need to visit the site), etc. The parts cost is calculated based on the actual replacement parts model and price, and the labor cost is determined based on the difficulty and time of the repair work. Travel expenses are calculated based on the travel mode and distance of the repair personnel. Generally speaking, the supplier will provide a detailed repair cost quotation based on the failure of the equipment, and the repair will be carried out after confirmation by the user.
