I will do my best to help any and all in the repair or diagnostic of any appliance.
My expertise comes from 30 years of doing the work and 20 plus of running and owning an appliance and HVACR company.
All I ask of you is to follow these rules and suggestions:


Remember to include your model and serial numbers in your post!

I can't tell you how many times loungers ask me for help repairing their appliance and they either give me a bad model number or none at all. Without a valid model number, I can't look up diagrams or find out anything about your appliance. So, here are:


the Ten Commandments for BikerEric's Online Appliance Help




1. Ye shall read the model number directly off the manufacturer's tag affixed to the appliance., not from the owners guide!

2. Ye shall use these diagrams to help you locate the manufacturer's tag if you are having trouble.

Window Air Conditioners

Dishwashers [partselect.com]
Dryer [partselect.com]
Freezer [partselect.com]
Stove or oven [partselect.com]
Refrigerators [partselect.com]
Washing Machine [partselect.com]
Trash Compactor [partselect.com]


3. Ye shall speak of the Brand Name

4. Ye shall mention if the appliance is electric or gas (natural or LPG [propane])

5. Ye shall speak of the configuration of the offending machine ie.side by side, front load

6. Ye shall speak precisely of the problem. not just it's broke , it doesn't work

7. Ye shall understand that I may ask for pictures if possible

8. Ye shall know and understand that I am doing this on line, So I may ask you to do a check on something. I have no idea how handy you are or what your abilities are, So you are doing these checks on your own responsibility. If you feel that it is beyond your ability , PLEASE let me know! BikerEric nor SlickDeals assumes any responsibility for your aptitude or abilities

9. Ye shall not blame BE if his diagnostics might be not be correct

10. Ye shall offer up thy praises in the form of reps or better yet as a donation to a local charity

11. Ye shall keep this tread "chit-chat" free and on topic

BikerEric's Online Guide to buying or replacing Major Appliances and HVACR


Please understand that I am very opinionated about brands and manufacturers . My opinions come my experience on working on these units and my dealing with the manufacturers. I scan the newspaper ads weekly to see who has the best price for the best products! I am not a pricing service. I do not work for or have any support from the manufacturers or from the dealers!


1 Ye shall explain what appliance you are replacing

2 Ye shall explain in detail what you would like to buy or purchase

3 Ye shall understand that my questions to you ( while seemingly personal) are to help you realize whether an appliance will work for you.



Ahem!
Ahem again

On the dishwasher, try checkeing the owners manual for a sequence of buttons to press to reset it.

Maybe you'll have to google it.

Whirlpool fridge (Gd5RVAXVY03)

Push button is stuck to remove water filter. This is the style where the filter is at the front bottom. Push the button and slightly twist and remove filter. The button is stuck in the the "in" position, so it won't move any further (or rebound back out). So filter is stuck. Any ideas on how to get the filter out?!

thanks!

Hotpoint Dryer model NBXR333EG6WW

Takes forever to dry clothes. I'm assuming I have to check the elements somehow? It is electric.

Question for you regarding sizing a Trane XV95 furnace.

Our current 80% efficiency gas furnace is rated at 100k which means it puts out 80k BTU. Ok, so when upgrading to a 95% efficiency unit, do I get a 80k or 100k two-stage unit? The smaller unit will give us nearly 76k output which is slightly less than we have now, but the larger furnace will give us 95k which is well over - and from what I understand from a couple of HVAC contractors, oversizing these units will lead to problems down the road.

Thoughts?

Are you happy with the heating capability of the current unit? (ie. 80K output?)

Actually, on the advice garnered from hvac-talk.com, I got a contractor to perform a 'manual j' load calculation to properly determine which size furnace to get. Ends up we went with the 100k (and getting it installed tomorrow ironically enough).

Trane XE1000 Airconditioner.

On turning the AC unit to cool, after a time delay the thermostat turns on the condensor fan, but the blower does not turn on. The pipes copper pipe (open pipe) next to the Blower unit was very cold. The entire AC box was cold. But the blower was not turning on.

Switched off the AC. Turned the fan position to On from Auto. The fan kicked in and started blowing air. So looks like the blower fan, capacitor and relay are good.

Was wondering why this fan is not starting when the condensor fan is on. This may freeze up the lines and destroy the condensor. Googling did not help me find a solution. Please help.

Could the thermostat be the cause of the problem or is it an issue with the control board on AC unit. Where can I get the circuit diagram for the wiring of the AC unit. Thanks in advance.

Try leaving the A/C on and switching the fan to "on." Does the fan still work then?

Tried the following:

1. AC unit off. Fan on - Blower works and sends air to house. [Indicates that the fan is working]

2. Fan on - Blower runs. AC on, hear clicking of relays in thermostat - Blower fan turns off. Outside condensor fan starts running. - Thus cooling down / freezing the copper cooling pipes.

Is the control board having the problem or is it the thermostat?

Any help is appreciated. Thanks.

My first suspicion is the thermostat. If you have another somewhere to test out, do so. Otherwise you can manually activate the blower and A/C unit simultaneously after removing the thermostat. This will tell you if tstat is the culprit.

with the fan switch on "on" the circuit board will shut off the fan, then kick on the ac, then kick back on the fan. does the same thing in heat mode if fan switch is in on position. you can check that heat works that way also.
im going with circuit board

How would I go about doing this. Is there any wiring diagram available online. Thanks.

Got the thermostat tested. Green wire is the fan. Yellow is the condensor. White is the Heat. Short the red to the green and yellow to get the condensor and fan to run. Only condensor ran, so looks like the control board on the AC Unit is having problems. Blue is the ground. DO NOT short Red and Blue this will destroy the 24 volts transformer.

By circuit board, do you mean the AC unit control circuit board or the thermostat circuit board? If it was indeed the AC unit control board, do you recommend any place to buy this for cheap and good quality?


Ok the Model Number for the Control Unit is 50A50-405
D340035P01 CNT1309

The AC unit states Trane XE-78.

Apparently this control unit is obsolete. Looks like this I will have to buy a 50A55-843 (some people have reported that this model works). Placed an order on Amazon.com
Will update with details on replacing the control unit.

Thanks

the fan is part of the furnace. has nothing to do with outside unit. newer units have a time delay before kicking on the furnace fan. heat and cool has the delay. heat is 30-90, ac <30 but stays on a bit after outside unit kicks off. the circuit board in the furnace has the fan wires connected to it and controls which speed. most have 3 wires, red blue black, black being ac(high).
what model furnace do you have.
if you do have the red,blue black you could hook the black up to one of the power connectors that isnt switched, on the board to get constant fan. " temp fix"

This AC unit is nearly 20 years old ( will become 20 years in 2 to 3 months). Hence has only a single speed fan. Funny thing is that the controller is a dumb controller. This should have shut off the AC condensor since the blower was not working. It was good that I was at home and noticed that the condensor was running and blower was not working, otherwise this would have been a huge expense to replace the frozen / broken condensor / evaporator coil units.

Replacing the controller did the job. Looks like the old controller died. Strange thing is that there should have been a built in feature of checking the operation of blower fan when compressor is on.
