Re: SAMSUNG AMERICAN STYLE- RSH1DTMH
It should be worth it.
It depends on if the insulation has been damaged by the defrost heater over heating.
This model had a lot of problems but is still better than the new Samsung.
If it is the age you say then it may pay to invest in a new one.
If you decide to replace it I would buy a Daewoo.
This make is normally reliable and Bosch / Siemens American style are just rebadged Daewoo but cost 3 Times as much.
