  1. Tony says:

    I have a porch light switch with 2 sconces, both have 60 watt incandescent bulbs in them. When I flip the switch it can take anywhere from 3 to 20 seconds for the light to come on. After reading, I’m inclined to stay by replacing the switch and then trouble shoot from there. Thoughts or suggestions?

    • Dave Rongey says:

      Hi Tony, One thing to consider is light bulbs. If the porch lamps do not have standard incandescent light bulbs then there could be a start delay. This is especially true for CFL bulbs that are used in outdoor light fixtures where the temperature is cold.

    I also have one light in my home that has a delay. There is a ceiling fan that is effected. The ceiling fan is connected through a SPST switch. There is an additional issue on top of this I think. The light kit on the ceiling fan will stop working after a while. There was a different ceiling fan installed that worked fine for about a year and a half. At this point, the light kit would stop working, first for a few hours, then longer, and then not at all. I replaced the fan, and the problem seem to go away, except the delay. Then the other night, the light stopped working, it turned out to be the bulb, but I replaced this last night, everything worked. When I tried to turn the light on this morning, the new bulb immediately blew.

      Hi Johnathan,
      The circuit wiring should be checked and voltage readings observed to look for a possible fault. Intermittent problems like this can be challenging to find, however in a case such as this, the starting point should be the electrical circuit.
      I hope this helps,
      Dave

      • Jonathan Schaefer says:

        Thank You that should help. However, I do realize I may have forgot a detail. The fan in question still works, just not the light.

        • Dave Rongey says:

          Hi Jonathan,
          The light fixture wiring should be inspected for a possible connection problem or a possible pinched wire which can occur when the light fixture parts are reassembled.
          I hope this helps,
          Dave
