The line voltage drops to 114-115 with the air con on, but I've used this same facility and outlet the past 2 summers in a row with no problem. The only thing that's changed is the place has installed solar panels. Could my power cord need replaced? Switching to propane or running a cord direct to the fidge does not work.

You have a refer cooling problem. You need to find out what is wrong with the refer. You originally stated just on 120 and now you state BOTH 120 and LP lack cooling. VENTILATION (Lack of adequate) is common to both modes. Is the refer in a slide out? Are you POSITIVE the rear bottom to top ventilation is not blocked? Doug

The 120 element efficiency is direct in relationship to the 120 line voltage. The LOWER the voltage under 120 volts, the less heat the 120 element delivers. What you need to do is measure the LINE VOLTAGE at the 120 plug behind the refer. I will bet, that since you are on a 15 amp circuit(you cannot/not advisable do that with an AC running), your load is causing the line voltage to drop. Doug

yes, low voltage to fridge
switch it to LP, until you move, or until cooler weather

15 amps is being overloaded by AC, Ref and converter. Switching Ref to propane might be enough to make it work. What is your voltage while you are plugged into the 15 amp? You need to know.
