Problem is a dirty capsule caused when fogged with humidity from breath it shorts out temporarily. it maybe possible to have it professionally cleaned but may need to be replaced. DO NOT USE FOAM POP FILTERS. Spend the money on a metal one. back off if you wanna save some loot.

Who sings this urban gospel song with these lyrics.. hint.. it's a woman singing. . "A journey, there my healing can begin. ohh a journey, where my broken heart can mend. Ohh a journey, if you need to...


BISHOP T.D. JAKES LYRICS

"Usher Me"


[Verse 1:]
Thank you for the roses to brighten up my day
Thank you for the tenderness to wipe my tears away
But when you see me drifting, sinking and needing lifting
Usher me into the presence of the Lord

Sleeping beauty fell asleep, in her bed of sorrow
It seemed like it was all she wrote, the end of her tomorrow
But God never ends the story without bringing back the glory
So usher me into the presence of the Lord

[Chorus:]
Usher me, there my healing can begin
Usher me, there my broken heart can mend
Usher me, I need to be restored
So usher me into the presence of the Lord

[Verse 2:]
Don't let pain discourage you, you know just what to do
When my heart is overwhemled, I lay my head on you
Though I still need mending, it's no offense to you.
Just usher me into the presence of,
Usher me into the presence, Oh oh,

[Chorus]

Power washer runs for about 10 seconds then cuts off


It sounds like your choke is turned all the way to "close". Find the choke and open it up about 1/2 way. This way, the corroborator can **** in some air as the engine RPM comes up to normal. If it will not crank with the choke as described above, then put it back like it was, crank it, and immediately push the choke handle over to about 1/2. As the engine warms, you can push it all the to "open" position (opposite of where it is now if my theory is correct).

Good luck, and if this helpful please take a sec to rate me. Thanks!

My alero starts up but it cuts off in 2 secs. i replaced the ignition and programmed it i guess that wasn't the issue because it is still cutting right off


Is your oil pressure sensor in working order, the pcm will allow the engine to run for 5 sec then shut the engine down if there is low or no oil pressure readings.

Start with that and post back, thank you for using fixya

Weathermaker 8000 furnance flashing code 31 blower comes on for 90 sec .. then shuts off .. then other fan goes on.. don't see any flames or lighting goin on can you help?


31 PRESSURE SWITCH DID NOT CLOSE OR REOPENED - If open longer than five minutes,
inducer shuts off for 15 minutes before retry. Check for: - Excessive wind
- Proper vent sizing - Defective inducer motor
- Low inducer voltage (115VAC) - Defective pressure switch
- Inadequate combustion air supply - Disconnected or obstructed pressure tubing
- Low inlet gas pressure (if LGPS used) - Restricted vent
If it opens during blower on-delay period, blower will come on for the selected blower
off-delay.

Neuman u87 strange sounds


Might be humidity. It's a condenser microphone and moisture will cause the hiss. I'm in a humid area with a couple of 87s, and that happens regularly.  Put it in a closed bag or container with dessicant and it will dry out the diaphragm. Alternatively, shine a lamp with an incandescent bulb on it to dry it up.

Neumann U87 is distorting and cutting out


As condenser microphones 'mature' they may accumulate contaminants on their diaphragms, which in turn provide a relatively low impedance bypass for the bias voltage. To check if your microphone may suffer from this effect, hold it close to your mouth and breathe (heavily) a few times on the head. The moisture from your breath will condense , and if there the capsule is compromised by contaminants, or if it has developed other flaws, you will hear an increase in frying sound and/or complete loss of output.
Sometimes the capsule can be cleaned, thus extending its useful lifespan. At the risk of causing irreparable harm to the heart and soul of the microphone, this procedure should not be attempted by an inexperienced specialist! If in doubt, sens the microphone to the Neumann Service Department in Old Lyme, CT or another qualified specialist.
