Ping. I had to pull the propex last weekend in order to solve the "5 blink" problem in the propex and the 40mm fan sticking. Any word on the new sensor for the HS2000 purchased Feb 2008?

Any idea when this new sensor will be available? Looks like I need to tear into the Propex again and it would be great if I could stick in the upgraded sensor. |
I will check with them and keep you posted.

The sensor upgrade for the <2.2010 units is available finally. A couple notes:
1) We will warranty (free) a new, freezer-cold tested airflow sensing fan and installation if you choose to go that route. We have found recently that 20-30% of the sensor fans stiffen up at sub-zero temps and cause the 5-flash shut-off. Propex was not aware of this but I have alerted them of this on older units.
2) If you elect to go with the new sensor, the sensor update kit costs $70.
3) In order to update to the new sensor, you must use full-length, non-shortened exhaust and inlet pipes. These cost an additional $20 each.
4) If the heater is still under it's 2-year warranty, any service work must be done by me or one of my approved warranty repair guys. |

Woohoo! Does this include shipping? How can I send you the money? PayPal?

If I remember correctly, the pipes in this picture from WestyVentures (which I copied when I installed mine 3 years ago) are shortened.
I'm kind of drawing a blank, here, is that true, Karl? Would these pipes need to be changed?
I've never had any problems with my Propex, but I have never been below zero, either. Is it prudent to do the upgrade?
Thanks...

Units built prior to February 2010 (A10 last numbers of the serial #) have the old optical airflow sensor. These weren't so picky about pipe length. The new Omron airflow sensor is more so. It is mostly the reverberation that upsets it, and full-length pipes eliminate the reverb.
Most of the early optical sensors are fine - in the end the quality control from their supplier led to some sensors spinning slower than others with the same airflow (the sensor wheel is a miniature fan). |

Shipping would be $5 on just the sensor kit, $10 if you need pipes also. I won't have more of the sensor kits available until I return from my roadtrip end of next week.  |

I've received the new sensor and hooked it up. There was a problem with the new sensor but I figured it out, it's not Karl's fault either.
The heater is working good now and it seems to be more robust. I can partially block the exhaust hose and the heater keeps on working, whereas before you would sneeze and the thing would shut off.
Thanks Karl!

Long-term report: I've not had any more problems with the Propex. It fires up every time and is working very well.
I know it is not recommended, but I extended the exhaust to the other side of the van and hooked back up a small lawnmower muffler. Even still it has been working fine!

No problems since FEB 2012, when I sent my Propex HS2000 (manufactured 2008 and never worked reliably) into Karl for refit. Again, zero problems after he fixed stuff. I don't believe new units will have the issue.
Repair Costs...
Propex HS2000 non-warranty repairs: replaced loose ignitor tip - $5, installed AF-delete chip - $25, cleaned&adjusted unit,installed parts,tested - 1.5 hours = $45 labor. Return shipping $20 UPS. Total due, $95.

Karl is really a standup guy, and stands behind his products.
Gots nothing but good to say about the guy. Heck he recently did a heck of a fast turn around on a repair for me and that was shortly after he had a very sudden and sad traumatic lost in his life.
Doubt that many of us could have handled his kind of lost and still focused so well. |

|
|
Installed a Propex that I believe the customer bought several years ago and never installed. It was brand new in the box, but I think it was from 2005. Anyway it won't light and I get the 5 blinks. I am going to try to blow some compressed air into the intake tube tomorrow morning and see if this does anything. Any other advice?

If it is that old, then yes, blow compressed air in the burner inlet and most likely the airflow sensing fan is stuck. Or, depending how it's been stored all those years, could even be full of spider webs!  |

Karl, would the propex not light because of there being no gas and would it not have any blinking lights?
I tried to start the other day when it was below freezing and it wouldn't light, then I attached a propane
tank and it fired right up. I am thinking the Westy tank is empty but the non blinking leds are a concern? |
Depends on the model. Which one do you have? |

| If it didn't give a fault code then that is odd. When you say it 'didn't fire up' what did it do or try to do? Did you hear the gas valve and ignitor? |

| Probably if you let it try multiple times it would eventually display a 2-flash fault code. |

Karl is there any chance that by doing this it could hurt the electronics of the unit? I don't want
to take any chances just to see if I get the two flashes when it clearly ignites from the added
tank. |
No, it is normal operation for it to try 3-4 times to do an operation before finally displaying the fault code in the circuitry from 2/2010-on. |
