Customer Question

The furnace technician that was out today showed me slight burn spot on the control board for my Rheem gas furnace Citrion II, it is 20 years old and they are recommending new heater. This company has been maintaining my unit for several years and appears reputable. Can I replace with just a board or should I go for a new heater? Also, a lot of corosion up the exhaust pipe, which he temporarily rewrapped until I replace.
JA: Did you double-check the thermostat? And what about the pilot light?
Customer: The heater works and is all programmed, just concerned about more of the control board burning causing it to shut down during colder temperatures.
JA: Do you plan on doing the work yourself?
Customer: No
JA: Anything else we should know to help you best?
Customer: I just want it to be safe, which the technician did not shut it down but he couldn't guarantee it would keep running all winter. Just wondered if it is easy enough to find a control board for a 20 year old Rheem gas furnace.

At 20 years old, if you can afford it, the best thing is to replace the furnace rather than spend 300 to 400 bucks on this one.You will have a new 10 year parts warranty and 20 year heat exchanger warranty.
