I don't have any new stuff. I don't want them. I have A 43 YO gas dryer. Right now, I have to replace the unobtainable ignitor I have about 6 spare s. I found out, I can manually light it with a spark for a short time bef ore it finally won;t light at all.
Not too long ago, I did a major rebuild and really discovered that I need t o do a major PM every 5 years and a minor one yearly, so i made that much e asier to do.
There is a bearing around the fan. If it fails, all sorts of problems happ en. I don;t know how to 3- print the seal. but in 40 years, the grease dr ied out. The NOS replacement had to have the grease replaced. What would really help is a electronic slip detector for the blower. I re-did the gre ase and changed the set screw to a brass-tipped one. I would like the set screw to fail.
I still need to re-build the lint catcher. I'll try to take some more meas urements when I put the ignitor back in. I;ll even try to determine the wir e used, cold resistance, hot resistance, voltage and current.
What I did on the last rebuild is I made it possible to remove the blower a ssembly easily by adding about 8 thumb screws and rivet nuts. On the previ ous service, I put rivet nuts on the outer panels.
The washer spits out the lint and clogs the drain. So, i made a proof-of-c oncept external sock filter and then borrowed a friend's lathe and made it really easy to clean the sock.
So, the most important thing, i think you can do for an electronic applianc e is to add surge suppression. I did that to a Carrier AC and I had mechan ical button problems on the thermostat. The electrical problem was a wie rd one where the backlight continued to stay on. The fix was to turn the H VAC system off for about 3 weeks and add surge suppression. Earlier I had to add a filter because the ECM motor was interfereing and breaking power l ine controls like X-10. The surge suppressor was a bidirectional 24VAC rat ed TVS diode installed at the furnace. A $2.00 part.
I have a story which really bothered me. Tracor-Northern had a multi-chann el analyzer that we were using on an SEM (Scanning Electron Microscope) to make a crude EDS (electron dispersive x-ray analyzer) and it died twice rep air was like $1000 for a $5000 USD instrument. It died after a storm. We had the schematic and there was absolutely no power line protection. I ad ded an ISOBAR and no more problems. Tracor-Northern said their specs said
120V 60Hz for power and we and we obviosly exceeded that.
The best surge suppression so far is a power conditioner (Isolation transfo rmer) AND a a surge supressor from OneAC/ Powervat such as the ISOBAR, Tha t method outperforms everything short of a UPS. The ISOBAR give you a conn ected equipment warranty and they honor it. I;d use it for a washer/dryer.
Sometimes, surge suppression can be cheap and other times expensive.
Whole house is also possible with and without an isolation transformer. W ith an isolation transformer the magnetocs limit the high frequency from ge tting to the other side. A word about isolation. It is and it isn't. The neutral-ground bond isre-made after the transformer.
Maybe the washer guys should put all of the relays on a separate, replaceab le board.
Power Condition, save the receipt, exercise the protected equipment Warran ty.
