Question about Goldstar DH504EL Dehumidifier
I currently have the above mentioned dehumidifier that the compressor runs fine but fan is shot? i checked all relays on mainboard all are fine and they click when switching to hi or low. what can i do with the motor itself possibly rebuilding it? it spins freely armeture is black but i cleaned it all with naphtha resistance specs are as follows:
red to black=03.3 ohms
orange to black=no resistance
orange to red no resistance
no continuity between red to orange or red,orange to black
also if rebuildings not possible what 2 speed motors can i look for in other appliances?
let me know
Problem fixed with the fan motor not running.
heres how i did it for anyone who experiences the same problem
1.) open back of unit(6 screws and pop tabs)
2.) with back cover open youll have access to compressor and fan-locate the blower assembly and remove the nut on it i used a 3/8 wrench from dollartree and rotated the blower fan while turning-its plastic be careful and remember righty tighty lefty loosey)
3.) with fan assembly off youll see the motor with 2 phillips head screws-taking these screws out with a power screwdriver allows the bearing assembly closest to the fan assembly,shaft,armeture and motor assembly to come out leaving rear bearing assembly attached to chassis
4.) once the motor assembly is completely out gently rest it against the fan hole and cut the silver tape being careful to ONLY cut the silver tape and the first white tape strip.
5.) youll see 3 wires and some insulator sleeves covering them leave everything alone except the ORANGE wire this wire attaches to the thermal fuse than to the windings
CAREFULLY heat up your soldering iron and remove the orange to thermal fuse connection than carefully thermal fuse to windings its a bit of a pain but can be done with patience
6.) remove original thermal fuse noting EXACTLY where original is placed on windings-it will have a small tape strip on it. replace it with one of EXACT OR NEAR THERMAL RATINGS a good choice is radioshack 270-1322. this thermal fuse is ratyed 10 amps max. but remember thermal fuses go by degree of heat and not by amp rating unless the amperage is in excess to melt the thermal material inside-my original fuse was 2 amps and 130 degrees celcius new fuse was 129degrees but plus minus 2 degrees so its a good choice and costs under 2 dollars
7.) place a heatsink clip or needlenose pliers between thermal fuse and solder connections BEFORE YOU SOLDER IT IN PLACE this prevents your 700 degree f iron from melting the fuse(remember its thermal not amperage were talking about here)
solder orange to thermal fuse with plastic extension than flat end to winding wire exactly opposite of how removed
8.) tape fuse in ORIGINAL LOCATION AS OLD FUSE i used scotch tape,place the thermal white protector piece on orange to fuse wire and push everything back down in original places-there should be no contact with any other wires etc. it will cause a fire
9.) once fuse is in place push tape you cut earlier back on and put 2 or 3 small scotch tape pieces of good length to secure the innards, lube the rear bearing of motor using vasoline- a few dollups will do it do the same for front slide motor winding assembly holding it in place than replace armeture with front bearing attaches as they came out secure the 2 screws back in place, put fan blade assembly back on(its keyed) secure nut and reassemble back
if you did everything correctly it will work like new just remember this time CLEAN YOUR FILTER SCREEN REGULARILY lol its critical for proper fan cooling
that should do it:)
