Ok I hope this is in the right place!
Our 1987 Bounder has 2x rooftop a/c units (coleman delta T) have replaced the fan motor & cleaned the evap coils to make it all as good as it can be.
Has been working perfectly before the freshen up & after.
Now all of a sudden as we are already hitting 100+ F days here in TX the compressor power is shutting off. The units have a low voltage protection built in (with light) that senses low voltage & cuts power to comp & keeps fan running.
Yet last year with constant 100+ days it never skipped a beat
The bounder is 30amp, with original longish cord with new plug.Upon reading another thread on here, mention of possible 30amp socket wear etc, so got a 50 - 30amp adapter and the 50amp socket is all nice & tight.
A week or so ago a similar thing happened on consecutive days & the 5th day the whole town power went out!!! So we thought just the town and not an issue with the bounder
But its happening again (to us) with apparently no one else having issues.Was fine yesterday & all night(only a degree or so difference) so kind of running out of ideas!!!
Dont think its the town again.. Would a shorter/new cord be recommended,
is it just the older design being too sensitive?!
I know with temperature increase, more strain on the town/park supply due to a/c's being cranked up/turned on ,fans etc. But the whole time the one unit we use has been perfect. Even after cleaning etc, even when its only the odd degree different.
No other appliance thats running in the bounder is having issues ie running slow or not at all.
Maybe it is just the old units power protection being too picky (I dont know if new units have protection systems that work differently and keep the compressor running but just lowers the output?) This 24 year old unit works fine every other time, just seems like power fluctuations kick the protection in. Yet people with 5ers etc still have a/c working.
Sorry for the ramble but pretty much out of ideas apart from a new roof unit. Or a portable unit inside connected to the power pole 20amp connection.
