Remove the power then remove the fuse. With an ohmmeter put the leads on both ends and read the meter. If it shows "zero" then the fuse is good and can conduct electricity. If it shows anything else than the fuse is defective and needs to be replaced.

∙ 7y agoAny fuse is checked for continuity to make sure that it is still operational. This is done with an ohm meter or a continuity tester. If there is a reading on the ohm meter or a beep on the continuity tester then the fuse is good. If there is no reading on the ohm meter, or nothing heard on the continuity tester then the fuse is open and needs to be replaced.

Can a 30 amp fuse replace a 20 amp fuse?
NO!!!! The fuse is your safety device. Never replace a smaller fuse with a larger fuse.Another answerPeople who have done that in the past have burned down their homes. Changing from a 20 amp to 30 amp fuse puts 50% more current through the wire, overheats the wire and can result in fire. Don't do it. As the above post explains, the fuse is your safety device.To Ad:The above answers are dead on. Remember the fuse protects the wiring from overheating and catching on fire. A 20 amp fuse is used on 12 gage wire and a 30 amp fuse is used on 10 gage wire which is must larger. Never mix them up.To Ad: actually if you people wouldve took some kind of electical class its better to put a bigger fuse.. you just do not need to double the size.. if you got a 20 put a 30 in it it want blow.. if you put a 40 then you will have problems...
