If the knob's shaft was solid instead of hollow, there would have been no problem.
In attempting to confirm that the set-point
adjustment worked, I foolishly tried using a tool to turn what remained of the shaft behind the
knob. 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). That drain tube goes directly outside, often terminating near
the compressor, or to a floor drain or to a small electric
“condensate pump” located by the air handler. At ARS Appliance Repair, we know that you have
a busy life and depend on your Jenn Air appliances to work
optimally every day. Regarding air conditioner issues,
it is not easy to decide whether it is the right time to replace or repair the
existing air conditioners. They also help in identifying and dealing with specific problems and then suggest the right Maytag parts
that will resolve the problem. Those with previous
knowledge will know right away whether the price is suitable, while those with no previous knowledge should probably write this down for future reference.
While it was completely intact, there wasn't much of it -
perhaps 1/16 inch sticking up though the "cup" where the suspension was located.

It seems that no two TC gauges ever use the same drive frequency!
If for some reason you wish to lower the frequency of the saturating core oscillator (for long runs and/or to
reduce RFI), turns may be added to both the primary and secondary
coils, but keep the ratio of the windings the same.
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. Now all I need is a DV-4D TC gauge tube!
Alternatively, monitor the output signal from the gauge tube and hand adjust the secondary winding position for minimum ripple, then apply hot-melt glue
or other adhesive to keep it from moving.
This is actually my second TC gauge using a
DV-4D tube.
The following applies directly to the meter movements in Hastings CVT controllers
using newer style meters with the blue and black logo, as well as similar newer style VT
meters (except for the stupid design part since there is
no know, see below). By checking out online
reviews and using local company directories and
magazines will assist narrow down the search. Shifting
its position down slightly exposed a much nicer surface.
Having your mixer-grinder, dishwasher, oven or any other appliance up
and running adds to your energy efficiency and also cuts down the costs
required for urgent replacement of parts or the product as a
whole. We carry most of the most common replacement parts in our service vans plus all of the necessary tools to complete the
job. Looking for a way to fix common problems related to appliances.
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.
Hiring a specialist appliance repairman may possibly not absolutely help save you
from shelling out dollars but least it could cqonserve you time and
preserve you from more problems. However, the very newest (current) versions may have fixed this but
I haven't seen one so I don't know for sure.
I also replaced the line cord which had seen better days.
After removing the front cover and set-point mechanism, the extent of the damage could
be seen. I normally consider damage to meter movement bearings to
be non-repairable but as I said, this was a challenge.
The broken meter looks like the meter portion of TC Vacuum Gauge and Pump Protector.
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).
I picked up this unit for $16 including shipping (just the readout
unit, no tube). OK, I really didn't have to do it as replacements for the entire unit could be found relatively inexpensively on eBay but I considered
it a challenge. The majority have learned on the job,”
