zombie movie a man try to fixe radiator but he turned to zombie and zombie eye are sensitive to the light
Is it Siege of the Dead (aka Rammbock: Berlin Undead)?
“Siege of the Dead” (which has the less cash-in-tastic name “Rammbock” or “Battering Ram” in its native Germany) follows a lovelorn sadsack named Michael who decides to travel to Berlin in order to drop in unexpectedly on his ex-girlfriend Gabi to return a set of keys in person. When he arrives, he finds her apartment occupied only by a handyman making repairs to her radiator. A handyman who is suspiciously non-verbal and given to occasional strange spasms. The handyman’s apprentice, a teenager named Harper, is a little more vocal and he explains that Gabi stepped out moments earlier. Before Michael can get in touch with Gabi, the handyman goes into full-on zombie mode and attacks the two of them. ----Siege of the Dead (Rammbock) (Movie Review) | Bloody Good Horror
