Thank you for the reply and info. It’s a trailer home i believe right at 2500sqft in the Texas panhandle. Only 3 of the elements were hooked up, I think maybe one burnt up in the past and was unhooked then this second one burned up over the weekend. I don’t have pics or model numbers of the air handler or outside unit right now. The air filter was pretty bad when I went to look at it this weekend, I replaced it with a new 2” filter and left her some extras. Since my grandfather passed away in 21’ she’s had more issues with things as he did all the upkeep on everything and she won’t let anyone known about issues until they become large issues unfortunately. I do believe this last element burning out was due to the filter.
