What should I do if the air conditioner in my truck camper stops cooling?
Jun 05, 2026
At MGK, customer support doesn’t end after delivery. When a technical issue arises, our team focuses on one goal: fast diagnosis + clear guidance + visual instruction, so customers can solve problems efficiently without confusion.
Recently, an after-sales case from a European customer helped demonstrate this approach in action.
1. First step: MGK team provided clear analysis based on video inspection.
Our customer reported a cooling with the air conditioning of his truck camper. After receiving the video, MGK factory technical team conducted a full review.
The result was clear:
l No error codes were displayed on the air conditioner screen
l The air conditioning system was running normally
l The issue was likely related to insufficient refrigerant
This quick visual diagnosis allowed us to avoid unnecessary disassembly or replacement and move directly to a practical solution.
2. Step-by-step video guidance for refrigerant recharge.
To ensure the customer could complete the operation safely and correctly, MGK team asked the factory to prepare an instructional video showing the full process.
The recommended procedure includes:
l Find the air conditioner’s outdoor unit in the outside back storage box.
l Add the refrigerant through the charging port.
l Add approximately 550 grams (about 1.2 lb) of refrigerant per recharge.
The video includes each step visually, making it easy for users to identify the correct position and avoid operational mistakes.
3. MGK strong after-sales support for global customers.
This case reflects MGK professional after-sales service:
l Fast response from technical engineers
l Clear visual confirmation through customer videos
l Factory-level instructional support (video & photo guidance)
l Simple, actionable solutions instead of complex technical explanations
Many customers are not professional technicians. For overseas customers, this approach significantly reduces downtime and service difficulty.
