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.

I have a RUUD A/C model UBHC-17J11SFF. The consensation pan has a crack. Can the pan be repair/removed without cutting the copper tubing?


not really you have to remove coil to replace pan. if there is room you can abandon that pan and put another under it.

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.

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.

Rudd furnace


You have a safety limit switch that is either bad or needs to be manually reset. Some have little buttons between the two wires going to the switch that you can push to reset. If not they are automatic switchs then one is bad. You have to do an ohms test to see if each switch is bad or good.

RUUD (Protech Model 500) Thermostat Single Stage Not Programable


problem is not the thermostat, thermostat is an on-off switch that happens to work on temperature. Your furnace is locking out. cycling the heat off switch resets the micro-processor in the furnace. You need to diagnose the problem in the furnace, to go further we will need the model and approximate age of the unit

Any will work provided you have it is a Heat Pump thermostat. I recommend honeywell or totaline.

Cannot reach the temperature setpoint in heating sequence


I think what you are trying to ask is should you use a 2 stage thermostat or stick with a single and just double the stages on a relay to work at the same time. As long as the relay can handle the amp load, there is no real need for a 2 stage heat system, unless you are concerned by the efficiency of $$. If I am missing the question please reply.
