The most common questions we receive from members of the Caja China community who are in the market for replacement parts are, 1) Do the pans fit both models, or are the 70 & 100 lb size pans different? The ash pan, drip pan, and charcoal grid are interchangable on all La Caja China AND La Caja Asadora 70 & 100 lb models. 2) At what point should I consider replacing my roasting box with a new cooker? If well cared for, your pig roaster can last as long as 20 years or more. We have customers who bring in models purchasing in the further back than that simply looking to replace a pan or grid. That being said, if your roaster shows signs of water damage, rust, or warping from prolonged exposure to the elements, our rule of thumb is that once repairs exceed $100 it is time to consider replacing. 3) When ordering parts for the China Box (also referred to as a "Cajun Microwave"), what is the typical lead time for delivery? We keep all parts in stock year round, so our turnaround time can be as quick as same day, with 1-2 business days as our default lead time.
