<span style="">We have a fancy new <span class="SpellE">ThermoFisher</span> TSX60086A -86, and it had a 2nd stage inverter failure a few weeks ago, about 2 years into its service life.

<span style="">Despite all the bells and whistles (including a sleek looking ~smartphone app~ that automatically notifies me of temp fluctations), troubleshooting it was a major pain that involved exporting logs via USB 2.0 port on the unit itself, emailing
them to the fisher reps, and manually silencing alarms from the touch screen on the front door every few hours for a few days.</span></p>

<span class="GramE"><span style="">Thankfully</span></span><span style=""> it was repaired under warranty, but I’d avoid this model if I were buying another one. If we hadn’t had another lab’s freezer in the building as backup, we would have lost all the recent
samples from two divisions!</span></p>
<p class="MsoNormal" style="margin: 0in; font-size: 11pt; font-family: Aptos, sans-serif;">
<span style="">The moral of the story, I suppose, is that the new machines are not always more reliable. I think chest units are a bit more reliable. <span></span></span></p>

<span style="">We have been very happy with the new iteration of the Thermo Fisher -80 chest freezers. Granted we have not had them for very long (maybe a year) – they were purchased to replace failing older models. They are a lot more efficient in that the
compressors do not run constantly. The freezer shuts down when it reaches temperature and only kicks in again once it warms up by a degree or two. This puts a lot less strain on the compressors and will hopefully mean they will last a lot longer.</span></p>

<p class="MsoNormal" style="margin: 0in; font-size: 11pt; font-family: Aptos, sans-serif;">
<span style="">Chest freezers are so much more efficient than uprights in holding temperature. Uprights lose so much temperature when the door is opened as the temperature literally just falls out of the freezer. Attached is a quote we received from Fisher
at the end of 2022 for both upright and chest however this includes out considerable University of Kansas preferred supplier discount – maybe UMich has something similar though</span></p>
