Having problems with your Air Conditioners ?

I have a Haier ESA3067 air conditioner that has worked fine for a couple years. Then it began to have trouble responding to the pushbuttons to raise and lower temp, etc. Now it has stopped running altogether. When the unit is first plugged in, the display lights up "88" for a few seconds, then goes dark. If the GFI on the cord is tripped and reset, the display stays dark. It will not respond to pressing the on/off button. Can the problem be fixed by replacing the touchpad? Or is there ano


Answers :

Yes, rightly said that it is the main controller unit that hass failed . It will worth a try to remove the board and reset the touch pads once again after resolderring on the connecctions of the microprocessor and the connectors to the display.
\015\012Check the main +5 volt to the micro processor, check the filter and regulator if the voltage is down.
\015\012If not a replacement board can be thought of , but a trail spare to confirm ultimately will be worth unless you can confirm if the mP is not oscillating at all.

I have 2 Frigidaire window a/c units, model# fam18eq2a1. The landlord tells me they are brand new. Both units have the same symptoms: about 30% of the time they power on and function normally.

Hello I have a TH232 programmable thermostat that manages my underfloor heating. Recently, it started randomly resetting itself whenever it calls for heat, i.e. when there's a light click. It then goes through a cycle of displaying everything on the LCD screen, then a 17, a 13 and then back to where it was. This also happens whenever I press ANY button on the faceplate. I am trying to contact Honeywell too, but they only seem to be based in Canada or France. Any ideas? Thanks DIY Don
