Lennox Whisper Heat start up

[leafs11cups]

@reedscuba there is no thermocouple on whisper heats dude, it's not a fireplace lol

[leafs11cups]

Whisper heat =cracked heat exchanger! Have a good tech check it with a see snake. 90% of all I see are cracked.

[Matic908]

Yup, almost all whisper heats are cracked. And the lennox pulse had a recall, check it out

[MrBigz30]

check the back of that heatexchanger,it is cracked,best way,with a water test or cutting a hole in the back of the furnace

[fetisov02]

@MrBigz30 um it's not cracked

[kumitetoday]

omg that light up was scary,:o)

[mechacc2000]

With the burner flames moving when the blower comes on there may be a crack in the heat exchanger. Get it checked out.

OMG DUDE. i'm uploading the video of what mine did upon startup. IT WAS SCARY.

[fetisov02]

every time i see one of these, I cringe..one of the biggest pile of shit furnaces you'll ever see.

[Samimi11]

Is that in regards to the Lennox WhisperHeat or all Lennox furnaces?

[ahutf]

I still have a working Lennox Pulse at my house. I check the heat exchanger once every year approx or bit longer, with an air test. Working on those old furnaces is fun.

[relimes]

Where are the inducer pipes?

[cwheels4]

this doesn't have "pipes". instead, it has a tall heat exchanger, and a draft hood to allow for proper ventilation to the outside.

Uhh, I thing '95 or '96.

[hvachack]

I love working on a lennox whisper amd G12s.. I replace just about every one I go on because of a cracked heat exchanger....

GO!!! Lennox!!!!!

[crazyredlion4500]

Yep I hated lennox . I Swear I will never work for another Lennox contractor again. I never saw so many failures and breakdowns on new equipment less than one year old. And having to deal with pissed off customers is not fun.

[1995bisquick]

why did the flame die out and come back im guessing a draft

[mt90945557]

I really don't know, probably a dirty flame sensor.

[reedscuba]

Bad thermocouple.

[REWYRED]

Except for the e-tronic ign and the blower motor the burners sound identical to the 1966 Lennox GS-8 furnace that was original to the house
