Description

Replacement cooling unit for Dometic 2551 and 2554. The letters before or behind the model number do not affect the cooling unit. These units are built at our facility in Shipshewana Indiana. Usually ships the next business day with FedEx/UPS Ground. If your fridge is older than 10 years, we highly recommend changing your heating element and adding an exterior ventilation fan to help the fridge run more efficient. An interior fin fan helps keep the ice buildup off the fins as well. Please note if your fridge is in a slide out, it’s required to have all air baffling removed from the top side vent and a slide out fan kit installed for proper ventilation and warranty purposes.
