Amana-Goodman B1037489S Heating Element

I got a 80's early model heating and air conditioning unit .the serial number not showing. How do I know what size heating strip goes in this unit. It has 2 breakers going to heating strip

Hi, the only way to find out without getting a local contractor involved is to prvide us the unit model number to check with the factory. If that information is not available then you will need to get a contractor locally to come by and check it out / repair it for you. Thank you.

What is the dimensions on this unit?

11 X 10 X 9”
