“What questions do you think are going
unanswered here? Think that Kennmore Washers are expensive!
Home warranties may make sense if appliances are expensive to
replace or nearing the end of their life span. If you have a faulty home appliance, then you must not wait until
the minor issue can become major and unbearable.
Also, if I bought a replacement for the entire unit, I'd then have yet another set of electronics without
a meter! Common problems with older electronics in general are dried up
electrolytic capacitors, bad connections, deteriorated wiring, and corrosion if used or stored under
damp conditions. Pressing "Load Hold" under normal conditions
will override the CVT-16 set-point and allow the load to be powered regardless
of pressure. Pressing "Reset" and "Load Hold" at the same time will override the fault and allow
the load to be powered should this be needed to remove the fault condition. It seems that no two TC gauges ever
use the same drive frequency! An off-center hole was drilled and tapped for an 0-80 screw that would adjust the
separation of the two "leaves".
There were a grand total of two (2) caps (one for half
wave rectified line voltage and the other for the low voltage derived from it -
4 uF at 150 WVDC and 20 uF at 10 WVDC). I have put TWO sections, further down this article, for do it yourself-ers (DIY).

With modern and scientific innovation there are
various technology has evolved in different types of fridges being
in the market. Replacing them with slightly larger values
from my used but tested stock, totally cleaned up the drive signal which was
a bit over 0.3 V p-p, just about right for the DV-4D TC gauge tube (there
is an adjustment of this if needed). This
is actually my second TC gauge using a DV-4D tube.
I still would like to find a DV-4D for this or my other gauge (which I also tested with the DV-4AM).
It uses a DV-4D TC gauge tube and has a useful range of 0.1 to 20 Torr so it is for the upper
end of medium vacuums. When I worked on repairing this unit, I didn't yet have a
TC gauge tube for either but was able to look at the heater drive signal with an oscilloscope
and inject a low DC voltage to simulate the thermocouple output to test the meter and amplifiers, if any (in this unit there are no
amplifiers for the meter). The main precautions to take
are to avoid blowing out the meter or TC gauge tube heater with excessive current - even measuring their
resistance with an analog VOM on the low ohms range may be fatal.
Figuring that this was due to dried up electrolytic capacitors, I opened the back of the meter
(all the circuitry is on a printed circuit board inside a metal
cover). The schematic of the VT-4 (courtesy of Hastings) is shown in: Hastings VT-4/VT-6 Readout
Circuit. Later, after noticing that the line regulation of the simple
zener circuit wasn't that great, and in addition, the reading was
drifting as the gauge heated up, I replaced the AC input circuitry with a low voltage power supply consisting of
a 12.6 VRMS centertapped transformer, full wave rectifier, filter capacitor, and LT1084 regulator set up
for 6.0 VDC, which was slightly less than what I measured
across the zener but the adjustment pot had plenty of extra range and that allowed me to use a transformer I had gathering dust
on my transformer shelf.
Simply remove the filter cover and pull lower rack out to
remove filter cover inside a dishwasher. After
removing the front cover and set-point mechanism, the extent of the damage could
be seen. It can be taken off by removing the screws and
sliding it forward. Avoid buying an automatic defrost freezer, which can decrease energy efficiency by up to 40%.
And if your freezer suddenly starts to take on a lot more frost,
or needs defrosting more than every couple of months, check the door again for a good seal.
Most customers don’t know this, have the inclination to investigate, or even want to take a chance
they’ll cause more problems than they already have.
For other responsibilities like marketing strategy and distribution and just general maintenance, I'll have other amazing
members of my team take care of that. General Electric
makes a wide range of appliances that have given the homeowner an edge that
previous generations could only dream about.
