This article provides a power series summability based Korovkin typeapproximation theorem for any fuzzy sequence of positive linear operators.Using the notion of fuzzy modulus of smoothness, we also derive an associatedapproximation theorem concerning the fuzzy rate of convergence of theseoperators. Furthermore, through an example, we illustrate that our summabilitybased Korovin type theorem is an advantage over the fuzzy Korovkin type theoremproved in the seminal paper by Anastassiou (Stud. Univ. Babe\c{s}-Bolyai Math.4 (2005), 3--10).
