I have a 1997 Palomino TXL-SC hard sided pop up camper that I’m renovating and I just noticed the A/C cord was getting really hot after a few minutes of use. I checked the prongs and the round prong somehow got squished. I don’t know how that could have happened. How do I fix this? I tried using pliers to squeeze it back into shape but it’s not budging. Another thing to note and and I’m not sure if this contributed to it but the cord attached to the A/C unit doesn’t reach the actual outlet and the previous owner had a 20V extension cord they used to connect it to the outlet. I know I’ve heard extension cords and sources that pull a lot of power don’t mix so I’m wondering if the extension cord could be the problem or if it’s the squished prong or both.
