If the set is working I would suspect that the coils are ok. The typical ones that go open are the primary of the antenna (will cause poor sensitivity) and the oscillator feedback winding (set won't receive any signals).
When you are measuring the resistance of a coil you are looking for something of a low resistance something like a few ohms to maybe 50 ohms.
