Fuse trouble

over the last couple of years i’ve had to replace about three fuses(thermal).
once as suggested with the high imit and safety. i always find the exhaust clear. very short run metal venting, exhausting fine .have removed drum cleaned any lint. this last time I found lint from maybe two or three loads.what I want to tell her is that your doing to maney loads in a row without cleaning the filter. does this sound right. cause in the past I think she cleans it before I get there. or is there:) another answer?
thank you dave
