2012 COACHMEN RV FREELANDER 21QB FORD 350 is very suitable for ordinary people to drive. It can be supported anywhere, and its length will not make people scary during driving, just like driving your FORD F-150. It has a shower with hot and cold water outside the car, so that you can enjoy the shower comfortably after playing at the beach, and its table can be removed to turn the sofa into a large bed, which can allow two people to sleep comfortably on it. The top sleeping area and the roof sleeping area have high-quality curtains, and the roof sleeping area also has a protective net to prevent children from rolling down. It also comes with an electric automatic exterior awning. Troubleshooting methods First of all, when using the generator, you must first check whether the air conditioner switch is in the off position. When the generator is started, the air conditioner switch must be in the off position before the generator can be started. If the following problems occur, please follow the steps below. Problem 1. The air conditioner and microwave oven do not work when the generator is used. It may be because the electrical appliances and sockets are used at the same time, causing too much load, causing the overload protection of the socket on the wall next to the toilet to automatically trip. Please press the button in the middle of the black socket and hear a sound to reset it. Another possibility is that the switch in the fuse box under the bed or under the dining table automatically trips, causing the switch to be in the off state. Please turn it on by hand. Note that while the generator is in operation, try not to use the air conditioner, microwave oven and socket charging at the same time, which will cause too much load and cause tripping. 2. In the absence of external power supply, the refrigerator does not work. Please check whether the light on the refrigerator is on. If the light is on and the refrigerator does not work, please check whether the propane gas is sufficient, and go outside to open the refrigerator control port to check the condition of the fuse. 3. In the case of an external power supply, the refrigerator is only powered by electricity. If the refrigerator is not cold enough, please try to press the refrigerator switch several times until the light is normally on. 4. If the gas stove does not work, please open the propane device door near the left door outside the vehicle and check whether the gas valve rotary switch is in the open position. If it is in the closed position, turn it to the open position. 5. There is no electricity in the 2012 coachman vehicle. Please turn the knob switch under the stove next to the door to the open position, or plug the outdoor cable into the power socket in the campground.
