goodman furnace

I have a gmp100-3 goodman gas furnace. When it calls for heat the main blower comes on and the status light blinks four times. according to the code, it's telling me the high limit or the auxillary limit is open, i replaced the high limit but it's still doing the same thing. Could both limit switches be bad?

why are you wasting money and time trying to fix it yourself? Just call a company and find out what is wrong with it then you get it fixed right.;
