It depends on what's wrong. If it's the front optical board on a Polar N7X/ N8X, the 639550 board is a fraction of the cost of a new fridge, and a new unit like the N8XF runs roughly ten times that. The product pages have current pricing. Most issues are fixable with a part, so it's worth diagnosing before replacing. Our troubleshooting guide and tech support service can help you figure out what's needed. Send us your model number and we'll give you options.
