Default Odd Sanyo 'Stealth Defrost' last night

Still using Auto mode, so far it's been working pretty well. At least when the line voltage is normal..
Running Hybrid mode, burning a little oil also.


I saw an interesting Sanyo event last night. The snow was getting real bad,
winds were blowing it all over the place. By the late evening, the outdoor
coil was so covered with snow and ice, the air coming out (using 500w),
was barely warm. But we waited for hours and it never went into Defrost mode!

I stayed up late, watching for the defrost mode to start. It never did.
So, at about 12:30AM, I decided to shut it down and go to bed.
The vent closed, the heat LED went off and the power dropped to 60w..

A normal shut down. I sat in the living room reading for a little while longer,
when I heard a little creaking from the indoor unit.?.
But, it was off.?. I looked at the TED and the power was creeping up!
And it was still off! Within a minute, it was at 800w.

Then, I knew! It was doing a Stealth Defrost! Within minutes,
it hit the top at 1280 watts and stayed there for about 10 minutes.
All the while making gurgling sounds. I scanned the indoor coil
and it was 32F.. But, no fan at all.. It was OFF after all..

So, I was getting the standard defrost, (Standard for Auto Mode)
but without any blinking LEDs.. After a while, it started to cut back
on power and slowly ramped down. Back to sleep..

When I looked out the window this morning, (It's still snowing)
I could see where most of ice and snow had cleared.
Only the bottom edge of the coil still had a little ice pack..

It's 28F outdoors and the Sanyo is working pretty well this morning.
But, I'll be turning it off later.. To see if it's going to do another defrost..


What worries me about running up power use while the unit is OFF,
it's not going to respond to remote commands.
I'll have to turn the unit on, and then turn it down, in case of over-wattage..

I hope it can be done fast enough. And Defrost mode doesn't lock out
the remote from calling for less heat..
