I have a 48 gal gas hot water heater that is power vented. It has a
problem and that the power vent blower cycles on and off after the
water heater has gotten done heating up water, like after a shower.
I am not sure where to start looking for the problem is there a common
part that needs to be replaced?
It is made by US Water Heater OF Philadephia and is about 20 years
old. It seems to be in good shape other than the problem. The model
number for the water heater is M-II-RTW50S5CN-8
thanks in advance,
