First it is a 1970 model mobile home.
second been here for 5 years.
third only one electric problem before soved by installing new breaker in panel for water heater with the right amperage.
Microwave,fridge,furnace,bathroom light,+1 rec( in bathroom ),+2 other rec. in kitchen. all on one circuit.furnace is naterual gas,eletric blower motor of course.
today the microwave went out bath lights dimmed and fridge light dimmed motor stopped running.also florescent light went out I had plugged in above sinc.no GFCI in this old puppy.so I installed a new 30 amp breaker in the box and all lights came back on but were very dim. so I unplugged the fridge and plugged it into another strong circuit and shut the fan switch on the furnace actually at the furnace off and every thing came up bright microwave works fine now.so i tried just plugging in the fridge all went dim again.so hooked it back to good circuit and tried turning on furnace again and it went dim again.
Question whats wrong with this circuit?
