Dometic AC Limit Switch - Fits Penguin & Blizzard Air Conditioners - Part# 3104133.016
The Dometic 3104133.016 AC Limit Switch is a critical safety component for Dometic Penguin and Blizzard rooftop air conditioners. This thermal limit switch monitors operating temperatures and automatically shuts off the compressor if unsafe heat levels are detected, preventing damage to your AC unit. If your RV air conditioner is cycling on and off unexpectedly, running but not cooling properly, or tripping the breaker, a faulty limit switch is often the culprit.
Key Features
- Genuine Dometic OEM Part: Factory-spec replacement ensures proper fit and reliable thermal protection
- Automatic Safety Shutoff: Protects compressor from overheating damage by cutting power when temperature thresholds are exceeded
- Direct Replacement: Designed specifically for Dometic Penguin and Blizzard series rooftop air conditioners
- Easy Installation: Mounts directly to compressor housing with standard electrical connections
- Durable Construction: Built to withstand extreme temperature cycling and vibration in RV applications
- Restores AC Function: Solves common issues like short cycling, intermittent cooling, and unexpected shutdowns

Frequently Asked Questions
Q: How do I know if my limit switch has failed?
A: Common symptoms include the AC compressor shutting off after running briefly (short cycling), the unit running but not cooling, or the AC not starting at all. The limit switch may trip and reset repeatedly if it's failing or if there's an underlying cooling problem causing overheating.
Q: Can I test the limit switch before replacing it?
A: Yes, with the power off, you can use a multimeter to check for continuity across the switch terminals. A functioning limit switch should show continuity when cool. If there's no continuity at room temperature, the switch has failed in the open position and needs replacement.
Q: Where is the limit switch located on my Dometic AC?
A: The limit switch is typically mounted directly on the compressor housing inside the rooftop AC unit. You'll need to remove the AC shroud and access the compressor compartment. The switch is usually held in place with a mounting bracket and has two wire connections.
Q: Will replacing the limit switch fix my AC cooling problem?
A: If the limit switch itself has failed, replacing it will restore function. However, if the switch is tripping due to actual overheating (dirty coils, low refrigerant, failed fan motor), you'll need to address the underlying cause. A properly functioning limit switch protects your compressor from damage, so if it's tripping frequently, investigate why the system is overheating.
