My bedroom circuit and microwave circuit are on a 15/20 amp tandem breaker. My microwave would fade out and bedroom lights flicker then nothing for a few hours. Then it would come back on. Replaced the breaker. Same problem. Took out the 110 volt light in bathroom, had power for 2 hours then all off again. Tested gfci, seems ok. There was a humming sound coming from outlet. At a complete loss. Breakers off for now.PLEASE HELP.2007 37' montana fifth wheel

Flickering, dimming. The circuit breaker(s) are either on or off. Sounds to me more like a loose connection somewhere, hot or neutral lines. If it is affected two different circuits after the breaker, it would be in the supply to the breakers or in the neutral bar.If your not comfortable working with 120volts get someone who is. check to make sure ALL screws on neutral buss bars are tight. or all connections in all boxes on the circuits.Yes leave the breakers OFF until rectified. Flickering dimming will cause circuits/connections to overheat arc, leading to bigger problems.Ken

Remove the outlet and look for heat issues.Also check in the breaker panel for heat issues on the neutral bus and breaker connection.

Great. Thank you. Will check nuetral bus and connections.

Get one of these, and monitor your voltabe, both in the rv and at the power post. Your problem may well be with the power source you are connected to rather than in your rig itself. The meter should always be in the green range. If too low, all type of weird problems may occur, including severe damage to your rig. easy voltage meter

If this power loss and flickering are only on one circuit, chances are that there are problems with a loose connection in one of the boxes/outlets on that circuit. Tighten & inspect all your buss connections first. If the problem persists, I would check that gfci next. Lights flickering and a buzzing sound from the gfci tells me there is a loose connection there or that the gfci is bad. If the connection is poor, it tends to fail after a period of time when used because of heat generated.
