Based on your postings, nothing you have done rules out overheating. Have you actually added an external fan to cool the receiver? As far as your temp readings after less that one day of operation, they are meaningless. It takes weeks of continuous operation for these temp readings to be really meaningful.Ok, my new receiver was working greate yesterday, and the temp was fine on it. I've been gone all day, and just got home. I went to turn the TV on, and lo and behold, this receiver is doing the same dang thing!!! This is really frustrating. What else could it be besides overheating, which it's not, or junk hardware?
Maintaining "minimum clearance" doesn't guarantee "proper" ventilation! You can have 10" of clearance around them, if you stick them in a cabinet they will overheat.Without external powered ventilation the 622/722/722k series receivers need a minimum of 4 " clearance on each side for proper ventilation (numbers are mine not Dishes).

These receivers are so poorly designed that the smallest airflow restriction will cause them to overheat.
You are right, these receivers run cold like a cucumber and I must be selling fans.You are really so full of yourself, you lessen your credibility. I have had a 722 in a cabinet for 3 years, and guess what, I've never had a failure!
gary s said:I had the problem of the green light coming on with fan running then it would turn off a while and then come back on time after time. Dish sent one or two replacements which immediately or soon (don't remember which) did the same thing.
I finally went out and reset the circuit breaker (turned it off and pushed it as far as it would go and then back on) for the circuit it was on and the receiver has been working fine for quite a while since.
I think the receivers are very sensitive electrically.
You might give it a try.
When my 622 was repeatedly crashing -- before I added the two external fans -- there was no warning, it simply crashed and then rebooted.Are those of you with overheating 722's seeing this warning, or is your disk just frying?
Two of my 722 also overheated without any warnings. Added an exhaust fan and it runs perfectly now.When my 622 was repeatedly crashing -- before I added the two external fans -- there was no warning, it simply crashed and then rebooted.
Considering how many, I mean many, have 722s that do not do that and you seem to have one right after the other, I think you've got an issue outside of the box. If it is not overheating maybe it has a power problem. Try running an extension cord to another outlet, preferably in a different circuit to see if that clears it up.

Interesting. I will certainly keep that in mind. It seems to be behaving ok since I unplugged my EHD. I am still thinking this a bad software update.
When you installed the new receiver, did you hook up the ehd before or after the receiver was authorized and all software downloaded?

If you listen here to "Bobby" the expert, these receivers never overheat and we don't know what we are talking about.
The installer connected it before.
When I got one of my replacements for my 722, I hooked up my ehd before I plugged it in for the first time. It would not power up. I had to unplug the ehd and then do all the software installation and programming downloads. Only once my receiver was authorized could I plug in my ehd.
So your receiuver worked after you unplugged the ehd. What happens if you connect it up again?
