Arizant Bair Hugger Model 775: Il dispositivo alla accensione da errore FC-009.

Mon, 12 Feb 2024 17:04:26 -0700

Staccato il connettore J4, misurata la resistenza fra cavo bianco e nero si ottengono 66 Ohm, fra bianco e blu da circuito aperto, fra bianco e giallo 260,9 Ohm.

Devo sostituire la resistenza? Oppure la scheda del circuito di controllo?

Dove posso ordinare i pezzi di ricambio?

Grazie.

All'accensione della macchina non si completa la procedura di autotest e compare il messaggio d'errore in oggetto. Come posso procedere per risolvere?

Il dispositivo è alimentato, il display si accende dopo la pressione del tasto (anche il backlight), mostrando tutte le icone presenti sullo stesso e rimane in questo stato. Non si sente il buzzer, nè i pulsanti non hanno più alcun comando. Mi potete aiutare a capire quale potrebbe essere il problema? Grazie

Appliance Tester: Load vs Non-Load Element Resistance Values

Mon, 17 Apr 2023 14:08:37 -0700

Hiya,

I'm writing wikis for home appliance repair and keep running into recommending continuity and resistance testing to validate whether a part is still working. I'm listing both acceptable or typical values for different load and non-load elements. Load elements meaning any component that consumes power, and non-load meaning unrestricted paths for electricity. Here are typical values of generic and specific elements.

Load Elements:

heating elements (0-120Ω)
- ice maker mold heater (60-80Ω)
- Samsung defrost Heater (120Ω)
- Whirlpool Defrost Heater (88Ω)
solenoids (on/off > 10Ω, and regulating < 10Ω)
motors (10-200Ω)
- Ice Maker Motor (400-600Ω)
- Ice Maker Auger Motor (5-50Ω)
- submersible pumps (2MΩ)
- Dishwasher Drain Pump (15-40Ω)
- Circulation Pump (10-100Ω)
Fridge Compressor (1-50Ω)
Water Inlet Valve (500-1.5KΩ)

Non-Load Elements:

switches (0Ω- OL)
Bi-metal switch (0-1Ω)
thermostats (and thermistors 2-220KΩ...simply check continuity)
fuses (<1Ω)

Future troubleshooters thank you in advance for Load vs Non-Load Element Resistance Values! Feel free to contribute more values in the comments or answers below.

Wheelchair: Wheelchair will not open fully

Sun, 30 Jun 2024 11:26:40 -0700

I have a Carex wheelchair for only less then a year, and the problem with this with wheelchair is that it will not fully open or will not spread apart at all. Upon looking closely or inspecting the chair as I push it down to open fully, I notice that at times the left or the right will not slide down, which prevents the seat from collapsing down to open fully. Because of this I am uable to open my wheelchair to open fully to allowed me to sit. At time when the wheelchair would only open halfway I have to sit in it in a tight position and Hopeing that with my weight it would force it to open up, which it dose sometimes, but now it will not open anymore. The part in which it needs to slide down which is the left and right is stuck, I tried WD40 by spraying and lubracating the bar and forcefully pushing the bar down. It work , but for only 4 days, now it’s back to square one. Is there anyone in the ifixit commmunity who are familiar with wheelchari repair, or knows how to disassemble the wheelchair? I have continuely have contacted the company (Carex) for support and help as to how I am able to repair this problem, but I have not heard or recieve any information at all. I do not want to pay addition $500 a new one, since this one is not even a year old. Please help. Thank You.

ResMed AirSense 10: Are Software Updates available?

Sat, 17 Jun 2023 13:18:11 -0700

ResMed CS reports that due to cellular updates, the CDMA can no longer connect to the cloud.

Is there a way to update either the device SW or the internal modem SW to restore connectivity?

Or a way to give it access to my WiFi so that it can "Phone Home"? ResMed says that I should ask my provider. But why should a respiratory therapist or doctor know that? ResMed should provide this support (or update) to their device.

Blood pressure monitor: Need a device that will monitor blood pressure during the day

Sun, 21 Jun 2020 05:30:02 -0700

I having problems with adjusting my blood pressure medications.

Does anyone know of a wrist device that will monitor blood pressure during the day so that it will alert me to either check it with a sphygmomanometer or take my meds.

This would help prevent me from going off on rants while answering iFixit questions ;-) And a lot of you are aware I can do that!

UPDATE 9/21/18

I was in hopes that the new iWatch 4 might help monitor my atrial fibrillation (aFib). I was just about to order one but found this article stating that Apple has promised it for later:
