Do i have a blown fuse if I am checking 2 small fuses that are on a circuit board. one is 1.6 amp 250v and the other is 160ma 250v and the 160ma fuse is the one testing 1.4 and the 1.6 amp fuse is tes

The power supply has failed. Replace the board.

A sudden load can be enough to cause the fuse to blow rather than a short. Replace the fuse either with a 250v 10A Slow blw fuse or us a 250v 15A standard fuse. If it still blows then there is a definite fault. Motor Loading from lack of Lubrication etc.
Or a wiring short. Fuses are available from many suppliers. The shape of the fuse being used and how it clips into the board will be import and. Take a sample or an iPhone photo with you.

My manual shows 4 different fuses.....The Outside SubWoofer fuse is a T2A 250V....Inside the Subwoofer There is a T4A 250V....I couldn't see the other fuse, and I assumed it was the same, then I find on the inside of the manual there is also a T1.6A 250V and a F200mA 250V
I have been trying to call Customer Service at 1-800-846-3000 but it's always busy.....

it is a 250V 15 amp. clip the fuse off the wire, close, and solider in a new one. Terrible design. LG should have to replace free or be sued !

The AH may denote "slo-blo" style as opposed to Fast-acting
A fast-acting fuse will look like a single strand of wire ( maybe wiggly looking) ..A Slo-blo will have an element in it and a spring

I can't believe he pulled them all, but here's a list of all the fuses and their ratings from the service manual:

S 1000 Fuse, T 5A IEC
S 1300 Fuse/Clip, 5 Amp, 250V
S 1801 Fuse, 2 A, 250V IEC
S 1804 Fuse, LT 1A, 250V, IEC
S 1805 Fuse, LT 1A, 250V, IEC
S 1700 Fuse, 2 A, 250V IEC
S 1701 Fuse, 2 A, 250V IEC
1003 Fuse, 500MA, 50V, UL

the fuse will always blow if there is a shorted component. the horizontal output transistor may be the most likely culprit, if you are not a technician, have it service by a qualified one.
