If you have had the unit re-flashed then this has problably deleted all your internet settings, if you contact your service/network provider in BC then I am sure they will be able to give you the settings so you can enter them.

The technician sould have replaced the circuit board with part number CESO11057-02 which contains a diagnostic LED that will blink out a code when a fault is senced. If not we have to diagnose the hard and costly way, test each circuit.

There are only a limited number of reasons why the blower would stop running, one being a bad blower relay and another being a overheating of the motor inself causing it to shut off on internal overheat. The relay is part of your circuit board and the overheat is inside the motor, both of which you had replaced. Has anyone checked for a restricted air filter or supply/return restriction? Loose wire?

I'm guessing now. Good Luck and let us know what you find.

Have you measured the temperature in the suppy plenum? Should be 140 to 160 max. If hotter, you have a blockage in the ductwork or vents closed. If within spec, bad circuit board.

Instead of air , it uses water to extract heat and send it thru the tubings.

Air To Water Heat Pipe Heat Exchanger


General Information
Air to water heat pipe heat exchanger is mainly to heat water using the hot air from heat recovery, it can be used for domestic water, water for boilers or production process. The exchanger is constructed using a partition in the middle to separate the exchanger, both sides are independently sealed. A single heat pipe can be replaced. While working the hot air flows from one side to the other side, the heat pipe absorbs heat. Meanwhile, cold water flows from the reverse side, the heat pipe releases heat, thus heating the cold water from the reverse side. The outlet temperature is not lower than dew temperature.
Field of Application
-feed drying
-cereals and oil processing
-chemical industry
Specification

Advantage:
-high heat recovery efficiency
-seldom temperature difference, fast heat starting, good isothermal
-the speciality of the heat pipe results in a high wall temperature, exhaust gas temperature can be reduced without reaching the acid dew point, avoid the corrosion of the equipment.

Core tube material: stainless steel, carbon steel
Fin material: aluminum, stainless steel
Tube/fin bond: extruded, high-frequency welding
Tube arrangement: staggered
Core tube external diameter: ?25
Core tube wall thickness: 2-3mm
Fin thickness: 0.4mm
Fin height: 12.5mm
Fin spacing: 3mm
Temperature range: 20~150?
Order Information
P/N Description: HP-XYZ-N
Note: X should be replaced into S, C
Y should be replaced into S, A
Z should be replaced into ET, W
N means the power needed
S-stainless steel
C-carbon steel
A-aluminum
ET- extruded
W- high frequency welding Air To Water Heat Pipe Heat Exchanger

Jeep patriot no heat


fan blows?
engine reaches and holds 180F or more , normal engine temp?
(use a IR pyro gun to measure it)
ever go a cooling system flush, if not the heater core could be packed full of junk.
id the dampers fail , its not in heat mode.
check the dampers after checking engine heat.

it only takes 2 things to make any water to air heat exchanger to work.
hot water
and actual air flow.

check for hot water first (engine coolant)

My bocsh 830es water heater will be running normal then will kick into a A3 mode no more hot water


Check for a green wire near the top right of your machine. It would loop back to itself with a little black heat shrink on it. This should be far away from the heat exchanger. if its near it, I would recommend pulling it out of the wire clips, and relocating it to behind the control unit on the right side of the machine. Keep it away from heat....its a resistor, and will pop random A3 codes if the heat increases its resistance. Reset your code and you'll be good to go.

My laars mighty therm keeps igniting on and over constanty, whats the problem


There is a problem with flame rectification. This could be caused by a dirty flame sensor, poor ground to burner, faulty ignition module, improper venting, inadequate combustion air, dirty burners, or clogged heat exchanger.

Water is flowing out of the exhaust for the heat exchanger. The tank is overfilling. we have checked all the pipes going into and out of the heater and they are clear.


The heat exchanger under the fan is leaking and filling the heaters lower cavity with water. It can not get out so eventually it backs all the way up to and out of the fan. The heat exchanger is an expensive repair but they do not 'fix' well due to the curved pipes. You can try a radiator shop but most likely you will end up buying a new exchanger.

Lately my four years old Laars Mini Therm makes whining noise when it runs; especially at night when everything is quiet. Please sugest what most likely the cause ... Thanks


Quite possibly a partially plugged heat exchanger either water side or gas side. The gas side would be soot deposits on the heat exchanger preventing the proper flow of comubstion gases from flowing out the vent, the water side would be scale build up on the inside of the heat exchanger.

My bunn coffee maker leaks water out the coffee maker.


You need to replace the washer kit inside the top of the maker. Remove the 3 screws that fasten the top and lift it off. You will see the rocker leaver that allows the water to flow into the tank. At the point where the rocker stops the water there is a series of washers that degrade from the heat over time and allows the leak. The washers are very easy to replace. The problem is finding the washer kit. I found it at: www.buyitnow64.com for $3.95 plus shipping (FedEx is only $9.98). I bought 2 (one for backup) kits.The original washers lasted almost 6 years. I had repaired this problem before with a washer from my shop but it broke down rather quickly from the direct heat from the tank. This washer kit is a Bunn washer kit that is supposed to fit all Bunn machines both residential and commercial.
Hope this helps. It took me 2 hours on line to find the washers!
