Frequently Asked Questions
Q: Is this board compatible with my Dometic RM1350 refrigerator?
A: Yes. The 3850964036 board is a direct replacement for Dometic RM1350, RM3762, and RM3962 2-way refrigerators that use the 3850964010 control board.
Q: Do I need any special tools to install this?
A: Only basic hand tools are needed — typically a Phillips screwdriver to access the control panel. No soldering or electrical expertise is required.
Q: Will this fix my refrigerator if the cooling unit is bad?
A: This board only addresses control panel and button issues. If your refrigerator's cooling unit (absorption system) has failed, the control board will not resolve cooling problems. Check for ammonia smell or yellow residue — signs of cooling unit failure.
Q: How do I know if I need the 3850964010 or 3850964036 board?
A: Both part numbers are compatible. The 3850964036 is the updated version. If your original board is labeled 3850964010, this replacement board is a direct, improved substitute.
Q: Does this come with installation instructions?
A: Yes. Basic installation guidance is included. The process is straightforward for anyone comfortable with basic RV DIY repairs — typically 20-30 minutes.
