Question about Ruud UBHC Air Conditioner

1 Answer

Ruud Model #ubhc-17j07sfd

Monday our a/c stopped working. We have tired the simple solutions like removing batteries from the thermostat, reset the unit using the switch on it and the circuit breaker. Nothing seems to work and we can't get any relief by opening the window because the air in south florida is humid and still. Please give me some advice on what I can possibly check myself, because calling a technician is financially not possible right now.

Cleanliness is the cause of many failures. Make sure the indoor furnace filter is clean. Make sure the outdoor coil is free of debris(you should be able to see light through the fins).

Finally turn off the breakers to the furnace and the A/C unit. Then turn them back on. This may reset them.

If ice has formed on the copper lines that protrude out of both the indoor and outdoor unit, Then shut the system down for a few hours. After it has completely thawed, reset the thermostat above 70 degrees. Thermostats set below 70 degrees have a greater potential for freezing.

Why did thermostat stop working?


First of all, remove the thermostat from the wall and determine whether batteries should be replaced. If fresh batteries are installed, you should be able to program it while it is detached. If this doesn't work, the thermostat may have failed and will have to be replaced.

How to wire a honeywell rth2300/rth221 to a five wire connection


I am not familiar with this particular thermostat; however, here's some general information; I hope this solution will help you troubleshoot.
Multiple Thermostats set in 1 zone will conflict; the one with the lowest setting will be the determining Thermostat. Here's an option you can try yourself; my solution is 'hard reset' the thermostat - afterwards, i'm outta options. invest in external thermometer battery/natural types; & manually turn t-stat ON or OFF; Additionally, keep an eye on how much draw your AC is doing on your meter.

setOFF manual; however do NOT change settings or power-off t-stat. I'd keep it on what you had intended it from day1. However, some may debate to turn everything off beforehand. personally, myself, poweringOFF the switch connected to your t-stat works. Remove battery and reinsert inverted; wait (5sec-1min); remove; wait 1min ('debatable' timeframe 5sec - 1min); reinsert batteries correctly; if you have a programmable thermostat; do the same with the hit 'reset filter' held down & wait 5-sec1min; observe roomTemp reading. May I suggest to keep an extra thermometer around to determine if temperature reading from the thermostat correct? Friendly reminder to turnOFF 'auto' mode during this hard reset. If reset requires reprogramming your t-stat, do whatever required to set your desired setting. cheers. best of luck.

from my understanding there are two types: programmable and non-programmable.

Thermostat keeps shutting down a/c system


A couple questions. Have you ever tried switching from auto-on while the system was working properly? And when it shuts down, does the blower in the furnace/air handler shut down as well? And the no batteries just means the thermostat is drawing power from the transformer in the furnace.

Rudd thermostat says battery power


Most new digital thermostats are design to run with battery or A/C power, unless the A/C power is connected to the thermostat via a connection to the common "C" connection to the furnace common the thermostat defaults to battery operation and that is normal. Batterys last from 3 to 5 years in the average thermostat.

Nikon d80 won't turn off. Stayed on after viewing slide show on TV. Operates properly with switch in "off" or "on" position. Tried:1. removing battery. it restarts with switch...


It may be as simple as a broken or worn out on/off switch. If the switch shorts out, the camera will always be on or always be off. The problem could also be the switching circuitry. If you need service, you should call Nikon's Service Department at 1-800-NIKON-US (1-800-645-6687)9AM-8PM EST, Monday to Friday.

My system uses a permenant air filter. It's missing. It's a Ruud Model UBHC-21J18SHG. What size filter should I put in this system?


The Ruud UBHC-21J18SHG has a nominally 21" cabinet width. So the needed filter is 19.75" x 21" x 0.375" (502 mm x 533 mm x 9.525 mm). The Ruud part number for the filter is 54-23217-03 .

The specifications sheet for the Ruud UBHC series air handlers is available here: http://www.coburns.com/images/PDFs/h22-517rev1.pdf . The filter size information is on page 3 and page 12.

I've found the filter at one online vendor: http://www.patriot-supply.com/products/showitem.cfm/RHEEM_68_101807_03 . (This is a common filter that fits several manufacturer's air handlers.)

I hope this helps.
