        Hello to all,

        Had my dehumidifier [dhmfr]running in an enclosed porch [12' x 10']. The porch is mainly windows 65% and walls 35%.

        After turning-off the dhmfr, I pulled the plug from a 3-pronged-outlet and one of the flat prongs was REAL HOT. Not like sizzling, but enough to worry me.

        The farm house was built in 1950. I beleive most of the wiring is 12ga and I had an electrican completely redo the service box in 1995. Is there anything else you need to know?

        Looking at options to determine what I can do to fix the problem.

        Thank you,
        tstex

        I would try running it from another outlet and see if it gets hot there. If it doesn't it could be a loose connection in the outlet.

        You can also see what is on the circuit besides the dehumidifier. The dehumidifier should have a plate on it that lists the voltage, current draw and likely wattage. The dehumidifier is less than 15 amp by itself, otherwise it would have a 20 amp plug on it which can't be plugged into a 15 amp outlet because one of the blades is turned 90 degrees from the other.

        A likely source of the loose connection is a "back-stab" outlet where the wires are pushed into a hole in the back of the outlet instead of being put under the screw.

If in doubt check with your local codes enforcement department for what is required when doing electrical, plumbing or structural work on your house. Permits may or may not be required in your area and home owners may not be able to DIY some tasks. I have no way of knowing if you have the skills needed to complete the tasks you are asking about, when in doubt seek professional assistance.

        My advice may be worth exactly what you pay me for it. :-) For the record I did not stay in a Holiday Inn Express last night.

        Thank you Sparky...I will plug in a radio to this outlet and start turning off 15-20amp breakers until i no longer hear music. I think the k-refrig might be on the breaker. I have felt the plug on other outlets before and it was not nearly this hot.

        I will also pull the plate and examine the wiring just to make sure there is nothing wrong with the wiring to the outlet.

        Thank you for your feedback - I will do so over the weekend and post back. tstex

        outlets are not forever, and loose or hot plugs indicate it's time to replace. you don't find tension gauges on the wall at the box stores, but if you don't have enough tension, there will not be good contact between the plug and outlet, and bad electrical connections get hot.

        good time to take a new plug around to all the outlets, and see if they are tight. replace all the loose ones to prevent possible fire hazards.

        I have had to shotgun two apartments (ssshhh! don't tell anybody!), the folks' house, and my house for creepy loose outlets. every. last. one. it doesn't cost much buying spec-grade outlets in 10-packs, and it's peace of mind, as well as keeping all the computerized electrothingies like media equipment and microwaves from going bonkers just when you need them.

        get a 3-light GFI tester when you buy the outlets, so you KNOW when you have shut off the breaker that the power is indeed OFF. only the lights should be glowing, not the handymen.

        If you are confident in your abilities replace the outlet and then test the plug trying to judge the hotness of the plug. Remembering plugs and cords do get hot when drawing current. But I am sure you know that as well. But since you mentioned that the plug does not heat up when using other outlets you may have solved your problem. Big Grin Good luck.
        According to the NEC when replacing outlets tamper proof type are required in most cases. While an outlet upgrade is minor it is still an upgrade. While that is splitting hairs but well worth the upgrade with the added safety feature. And we are talking about switching out a 55 cent outlet for a 2.50 device. Just one more think to think about.

        Replacing and testing is no problem...loose wiring and old wiring is always an issue. I am going to count the AMP's used on this circuit both fixed and then variable and determine the loads/any constraints. I also think replacing older plugs/switches is always a good idea, if they look beat-up or worn - thank you, tstex
