Honeywell CM927 display issue

[michellesooty87]

Hi,
Does anyone have any ideas regarding whether this is a complete failure of the display? Batteries changed this evening. Long overdue. I've read about display cells failing but this is a case of every single one being ON.
Help please

Have you tried hitting it with a lump hammer?

I do not fit these anymore as I had a shed load go faulty after about 18 months. I would change it to a new one to be honest.

Good advice. I thought that. Can you recommend a decent new one?

I have HIVE active heating in my own house. But depends on your needs. What would you like it to do? I.e. internet enabled or just a timer?

 

[michellesooty87]

I can't be bothered with going through wall chasing for NEST or anything internet based. Also my internet connection not that great. I was just thinking about a reliable wireless portable thermostat with receiver

Have a look at the Honeywell T4R fitted a couple but not been out long enough for any faults yet really.

 

[michellesooty87]

Ok, I will do.
Thanks for all your help and advice. Might just do the lump hammer as well

Honeywell have buried their heads in the sand over the terrible reliability of this product.

I've swapped products out and away from honeywell.....

 

[Harvest Fields]

So did I originally. I went to hive and Drayton. But the T4R isn’t bad.

 

[Murdoch]

^^ honeywell should, and could have done far more .....

 

[Harvest Fields]

Yes mate they should have. But at least they have changed their whole design now.

Still haven't admitted there's a problem with the old ones tho

Nope and I had to fight to get one done under warranty that was bang on 12 months old

Mines out of warranty but I've still emailed them asking what they can do about it, as it appears to be a known fault. I'll see what they say

My son had a five year old CM907 on which the display broke up. He emailed Honeywell, who replied asking for a pic of the display and the date code on the back. He sent this off and received a reply agreeing to the replacement. They asked him to send back the old one - Freepost - presumably so they could make a claim against the manufacturer of the LCD component. Looking at your pic, the wired and wireless versions all use the same component.

Doesn't look like the usual CM927 display failure to me, where segments progressively stop working. It's more like a manufacturer's display-test mode. Try taking the batteries out, pressing the 'i' button on the CM927 (to run down any residual charge) and then reinstall the batteries.

Thank you. I will give it a go and see if this possible fix makes a difference.
Cheers

Honeywell have contacted me back saying my guarantee is with whomever bought it or what shop?
I have no receipts and it is out of guarantee. I think I need a new one but I will give the running down the charge a go first by removing the batteries .
