Coach, to figure out what's happening with your GFCI, you first have to know how it works. Breakers operate on heat generated by electricity. As the breaker heats up the spring inside expands and trips the breaker. That's why you can't reset a heated breaker until it cools. The GFCI is a different animal. It monitors current flowing through it. If there is a difference in current draw, it's designed to trip. You can reset it as long as the current is constant. When it differs, it trips again. This is just basic stuff, however. If you want to know all the technical stuff, a Google search will give that to you. Now to your issue. The GFCI will be placed somewhere on a electric 'run'. That is a series of receptacles placed downward from your electric panel. It doesn't matter how many receptacles are on the run, there could be a dozen. However, the ONLY ones that are protected by the GFCI are the ones downstream from the GFCI. So, if it's in the middle of the run of a dozen, the first six won't be protected but the end six will. GFCIs will go bad and they are a pretty cheap fix. I would start there. Because two outlets cause it to pop it's most likely bad. However, it may also be something as simple as a loose wire in the box. This happens because electricity generates heat and heat will cause the wire to expand and contract, loosening the wire in the receptacle. Loosen the GFCI and check for loose or corroded wires. Do the same with the other receptacle and any others downstream of the GFCI. If you see none, stop by your local hdwe shop or Home Depot and pick up a new one. Replace the GFCI and see if your issue goes away.....Dennis
