I turned the heater on one morning and was working fine. The next day I turned it on and it was blowing cold air. I have replaced the thermostat and still won't blow out hot air. Fan works fine. A hose was also replaced due to wear on hose. Still won't work. I can't figure out what is wrong, could it be the core in some way and how would I know that is the problem
have the same problem?
